Daily Report for Sunday April 30

EOP last night to 20 UT today.
Fine, sunny and very warm.  Light northerlies most of the day,
with some variable winds during the afternoon. Little cloud,
except along the mountains.

Soundings this morning from Independence Airport reportedly found
that the northerlies were shallow and that's consistent with the
profilers.

MISS profiler pc has some network problem and so consensus files are
not being transmitted to the data manager.  The raw spectral are
being recorded so the consensus data can be recovered post-project.

Last day of the project.
Sodar-RASS still down so we dismantled that this morning, and then
dismantled the rest of the sodar this afternoon.
Data backups of the various systems is continuing.
The rest of tear-down will start tomorrow.

Brian has arrived and is helping out, and so is Laura.

Daily Report for Saturday April 29.

EOP last night and another EOP tonight.  Soundings from Independence Airport.

Fine and clear with light winds.  Winds were northerly last night and this
morning, and switched to southerly around midday suggesting good conditions
for an EOP.  Small scattered Cu clouds during the afternoon.

All systems working with the exception of the RASS part of the SODAR-RASS
(see below).  Surface met at MAPR showed an interesting 30 deg oscillation
from about 5 to 12 UT last night (period abit over an hour).  Increased
range of MAPR RASS signal as it's getting warm during the day.

SODAR - RASS : RASS RF system failed a couple of nights ago.
Repeated power cycles have not restarted the system.
Tried measuring signal using the spectrum analyzer - RF signal was just 30 dB
above noise level - this is weaker although the antenna cable to the
analyzer was not in good condition so it is not clear whether the problem
is due to weak tranmitted signal or a receiver problem.
The crosstalk meter on the receiver is not registing anything which does
suggest a receiver problem.

Daily Report for Friday April 28

Fine, clear, and warm. Breezy at times, northerlies all day.

EOP planned for tonight and tomorrow night.

Moved MISS back to the base site at Manzanar.
A videographer filmed the move.

Set MISS and ISS2 profilers into 60m mode for tonights EOP.

MAPR still in wind200_rass10_30min mode.
Now running bird algorithm SAM parameter set to 0.8 for all runs.
(Changed 23:19UT Apr 28).

Daily Report for Thursday April 27

IOP 15 ended this morning - last sonde at 17UT.
Mainly cloudy, esp south of around Division Creek and over us.
Cloudy level fairly high, about Sierra peak level.  
Could see some lenicular wave clouds over this area from Big Pine this a.m.
Cloud broke up later in day, mainly clear this evening.
Mainly northerlies apart from some southerlies this afternoon. Breezy.
Occasional very light precip.

There appeared to be some high freq (around 10 minute) oscillations in 
SNR and w this morning so we may have been seeing some wave activity.

ISS2 profiler running okay.  Some persistent updrafts, not clear if due
to a standing wave or up-slope flow.  Perhaps some reverse flow 22UT.

The MISS generator stalled last night - Lou it restarted okay - there was
a break in the SOAP processing, however the data was collected so those
plots can be recovered.  NIMA processing also suggesting persistent
updrafts.

MAPR running well. Doing bird algorithm tests overnight tonight.

Daily Report - Wednesday April 26

IOP 15 is underway to study easterly flow.
There's a cut-off low to the south that's producing the easterly flow 
over the valley. 

Weather cool with light variable winds.  Mainly cloudy.

We did see some reverse flow at all three profilers, with westerlies
at low levels with easterlies aloft.  Possible rotors.
These were at MISS at around 16UT, at MAPR around 20UT, and at ISS2 at 23UT.

ISS2 profiler stalled after the wind consensus at 0UT (Apr 27).
Restarted okay.

Put MAPR into 200 meter mode at 3UT (Apr 27), attenuator set back to 4.

Daily Report for Monday April 24

Fine - some cloud in afternoon, light winds.
Cloud along the mountains all day.

Moved MISS to Kiersarge Mine site in preparation for IOP 15
which had been due to start tonight, but has been delayed until
tomorrow night.

MAPR down last night due - minicom message was temperature fault
but the weather was cool and the fans were running okay.
(See separate tklog entry).
Jason and Lou cleaned out the filters, although apparently they 
weren't that clogged.  Pressed blanking to fix.

MISS and ISS2 rental generators were serviced this morning.
Lou and Jason also changed the oil on the MISS built-in generator.
 

Daily Report for Saturday April 22

Clear this morning with increasing clouds and snow showers along the mountains.
Cool, mainly southerlies, breezy at times.

Various maintenance activities, and training Jason on the ISS and sodar.

MAPR stalled during the day and had to do manual restart
(see separate tklog entry), otherwise everything operating normally.

Jason refueled the MISS and ISS2 generators.  
Generator service scheduled for Monday morning.

Next IOP probably Tuesday.

Daily Report for Friday April 21

IOP 14 started with a sounding at 1am (8Z), the last sounding was at
Independence Airport at 4pm (23Z).

This was a south-westerly flow event, producing strong southerly winds 
in the valley.  There were occasional high wave clouds to the south, and
at times a line of clouds along the western and estern sides of the valley.

There were a few periods of persistent vertical motion on the profilers,
particually MISS which was at it's base to the south.

Soundings went smoothly. The 20Z one showed classic wave critical layer
behaviour above the tropopause so the Leeds crew launched a 350g ballon
from the airport to try and probe to higher levels (we helped them as
that was a little tricky in the high winds).

Rainy weather for the weekend with probably no IOPs until Tuesday.

Daily Report for Thursday April 20

Fine, clear, light winds. Some thin high cirrus.

Some soundings were apparently launched from Independence Airport last night
to catch EOP type conditions.

Profilers were still running in 60 m mode from previous nights EOP.
Switched during today to settings for IOP-14 which starts with soundings
from 1am tomorrow morning.

Note that for some reason, the 100 m winds at ISS2 are going into prof915h
rather than prof915l (so the winds data is currently in the high mode plots).
This is not happening at MISS.

Fixed a radiation sensor problem at MISS (see MISS tklog).

Gave a tour of some of the sites (MAPR/MISS/ISFF central tower/Azi lidar)
to Bob Street (Standford) and some of the students.

Mike left today, replaced by Jason.

Daily Report for Tuesday April 18.

EOP 3 started at 4 pm (PDT) this afternoon.

Fine and clear with light winds.  A little cirrus.

MISS RASS turned back on this morning after Lou's repairs to dishes.

Cleaned out sodar.  Brief interuption to sodar-RASS at around 22:30 UT.

ISS2 Profiler put into 60m mode (MISS was put in 60m mode yesterday).
There seems to be a little less RFI in this mode.
Profiler PC stalled for a couple of hours from 23:30 UT.
Occurred at end of consensus so may have been a hang during data transfer 
to the data manager computer.

Gary's last day in Bishop.  He did some up-grades to the MAPR software
(see separate log entry) and some data backups.

Daily Report - Monday April 17

IOP 13 Ended with the 8 UT sounding at MAPR this early this morning.
Yesterday afternoon and evening there were a lot of short wave length 
waves and/or rolls - MAPR saw strong vertical velocity fluctations 
(period of around 10 minutes).  Some easterlies (eg 23Z-5Z).
Visited REAL and saw the waves and rolls in their RHI scans.

Today mainly fine, clear, and cool with a light southerly breeze.
Some high cirrus.

Moved MISS back to the base site.   Switched MISS to 60m mode for
tomorrow night's EOP.

Lou has arrived and is straightening us out.

BTW See ISS2 tklog for yesterday's daily report.

Daily Report - Friday April 14

Cloudy with southerly breeze.
Perhaps some wave clouds along the mountains.

Moved MISS from the base site to OV2 (1.7 miles up Onion Valley Rd).
Profiler started there around 23:55 UT.

A hint of RFI at MAPR (eg 0 - 1 UT Apr 15) however minor and not
enough to cause any problems.

IOP-13 starts tomorrow afternoon (20UT).

Daily Report - Wednesday April 12

IOP 12 Ended Early yesterday evening as the event weakened.
The profilers all worked well - with all profilers measuring winds 
(mainly westerlies) up to 3.5 - 4 km during the day yesterday.
Mainly downward motion at ISS2 and MAPR, and upward at MISS.

Today was clear with a strong southerly breeze.

MISS was moved from the Kersage Mine site back to it's base at Manazanar
(see the ISS1 tklog entry). 

MAPR changed to 200 meter mode this evening (around 2:25UT Apr 13).

Hal left yesterday, and I (Bill) arrived to see out the rest of the project.

Daily Report - SA April 8
We're in IOP 10, seems so far like more of an EOP. Currently winds are 
from the north and west at the surface of MAPR site. 

We moved MISS yesterday to Division Creek site. There was a lot of ground
clutter and RFI... We rotated the trailer trying to correct for these problems
by pulling the truck in sideways and turning the trailer 25 degrees to ~240
on the compass. This did help some, but looking at the SOAP plots I see a lot
of high level SNR, which looks like non-atmospheric signal. The plots created
NIMA seem to have cleaned up the crapola!

Instrumentation:

Had to adjust the attentuator because of VSWR faults earlier last night.

Changed from wind200_rass100 to wind100_rass100 at 1517 4_8_06 UTC.

peaks clear, valley clear, light winds, currently from the NE. 

This morning the valley was cloud covered from north at bishop down to independence, but about 10am it started clearing in the center from Bishop slowly to independence. It was cleared by noon even south of Indy. 

Checked the surf tower and didn't see any obvious problems. 

Barb and _ helped me do the morning sounding. Something happened to the TKLOG entry for the sounding. The weather description changed. I left them to finish it while I fueled up MISS. 

MISS seems fine. Used about 1/2 tank of fuel or approx 20 gallons. I also filled the tank in the back of the green truck with 40 gallons, about 1/2 a tank.

Daily Report - Mon March 27

Very nice calm day with pretty good coverage of high clouds.

We (Brian P, Brian B and I) moved MISS from Site 'D' to Manzanar 
base site. We are awaiting package from Lou. Brian pieced back the
rest of the tower.

IOP 7 is scheduleds to begin at 11 UTC Tues March 28th.

Daily Report - Wed March 29

Weather: Post frontal with convective showers over the Sierras, some
showers passing across the valley. Light winds.

EOP#3 scheduled to start at 3 PM today with soundings launched from
IND airport every 1.5 hours.


Instrumentation:

RASS profiles at MAPR look better.

MAPR still operating at wind200_rass100 mode, will switch to 
wind200_rass100_30min for EOP.

Trh from MISS back on track after loose connection on campbell logger 
was found and battery recharged.

MISS anemometer being repaired today.

Daily Report - Tues March 28

Weather: Very cloudy today with low clouds even in the valley. Numerous 
rain showers throughout the day increasing in coverage by late afternoon.

IOP#7 was cancelled at 16 UTC due to excessive cloud cover. Soundings were
launched at 11, 14, and 17 UTC (14 UTC at MAPR).

Spent several hours with Hal Cole going over the systems and visiting the
potential MISS sites.


Instrumentation:

RASS profiles at MAPR of questionable quality.

MISS tower inoperable throughout much of day.

Daily Report - Sun March 26

IOP6 ended with a bang with very strong winds buffeting the region.
Locals in Independence claim they were the strongest winds in
town in 15 years. Some moderate damage due to falling limbs was
reported.

We are licking our wounds after the ferocious winds. Lou will
send new RM YOUNG prop vane to replace the one damaged when the
tower fell. Brian will try to put the rest of the tower back together.

Mild calm day today with high overcast.

Instrumentation:

Performing some tests with MAPR

Changed from wind200_rass200 to wind100_rass100 at 2015 - winds became noisey
Reduced attenuation back down to 4, noise removed

Daily Report - Sat March 25

IOP6 continues. Beautiful wave cloud over Owens Valley as I was driving
in this morning. 

Goal is took look at coupled mountain waves - rotar - BL system

Weather: Highly variable across the Owens Valley, A rotor passed over
MAPR around 1800 UTC.Rotars continued to pass across the valley with
surface and profiler winds alternating between easterly and westerly
and pulsing in strength with the pulses getting succesively strong
with time. The last couple of pulses exceeding 20 m s-1 caused brief
power outages at the trailer - wrecking havoc with the MAPR transmitter.
The last surge was associated with frontal passage with winds shifting from
very strong westerly to northwesterly. At this time the MISS tower
was blown over- badly damaging the prop-vane anemometer.


Instrumentation Status:

MISS had ground clutter issues again(signal returns showing up down low
at +/- 17 m s-1) overnight.

MAPR had intermittent transmitter problems (1945-2200 UTC) caused by a brief 
disruption in power.

Data from MISS IR sensor are of intermittent quality.

MISS tower toppled at 0300 UTC.

Other: ASU sodar operating (fully attended)

Two sondes were launched during peak of winds, but were unable to lock
onto GPS. We found you must make sure GPS is locked in before launch,
especially during high winds.

Daily Report - Friday March 24

IOP6 began at 20 UTC today.

Goal is took look at coupled mountain waves - rotar - BL system

Weather: Warm and light southerly winds, alot of high cloud
around, bands of lower stratocu moving in during the afternoon.


Instrumentation Status:

MISS was moved to an old Sierra Rotors site (accidentally), however,
this was a good site close to hwy 395 in between MAPR and OV site,
but shielded from the highway by dirt piles to the east (see photos)

MISS had ground clutter issues (signal returns showing up down low
at +/- 17 m s-1) during the previous night which seem to have cleared 
up today.

MISS IR sensor problems starting 16 UTC Mar 24.

MAPR sonde issue (no gps) - problem was loose connection with GPS antenna.
Problem solved by talking with Tim Lim.

Other: ASU sodar not operating - company rep here to examine it.

update: ASU sodar Appears to have been fixed late this afternoon.

Daily Report - Wednsday March 20

EOP #1 began at 23 UTC today.

Goal is to look at overnight evolution of the BL during quiescent period.

Weather: Warmer conditions than the past few days, light winds and 
alot of high clouds (cirro-stratus) around. 

Today's EOP is planned to extend until noon tomorrow.

ASU sodar not operating.

MISS MotoSat problem was corrected around 4 PM today.

MISS radar had some serious RFI between noon and 5 pm today.

Daily Report - Monday March 20

IOP #5 began at 15 UTC today.

Weather started out calm, sunny and mild. Winds began increasing around 
12 noon LT and Fohn cloud set up and rapidly spilled over the Sierras 
and spanned most of the Valley. Took some pictures while the Fohn wall 
deteriorated and clouds advanced across the valley.

All instrumentation seems to be performing adequately.

The sonde Charlie was using to test the software bug could not be
reused.

IOP #5 will end at 06 UTC March 21 (or 10 PM tonight).

Daily Report - Sunday March 19

Informed at 2 PM that the project would like to move MISS
to OV2 site.

Despite short notice we were able to tear down and redeploy
MISS in about 3 hours. See MISS log for details.

Note: Had anemometer on backwards initially, redeployed it properly.

The datastorm system seems to be back to normal now. 
The receiver is staying locked on. 

Yesterday, when we were having problems, the wind
was strong from the north, and the motosat dish was 
rocking back and forth by several degrees in elevation.
I wonder if that could have caused the problems?

Daily Report - Friday March 17

Profiler at ISS2 trailer was down between 00 and 20 UTC March 17.
It appearantly froze at 00 UTC yesterday while calculating concensus
winds (see ISS2 log for details).

Scintec sodar/RASS not working today.

All other sensors appear to be functioning well.

No IOPs scheduled for Sat or Sun.

Visitors at MAPR today Mike Daniels and Sharon Zhong (U. of Houston).

Daily Report - Thursday March 16

MISS generator was serviced today - down for ~ 2 hours (9:30-11:30 LT).

Rotar seems to have developed this morning, Vanda requests that MISS be
left at current site. 

Steve and I restarted generator and brought up all the systems.

Visited all 12 alternate MISS sites with Steve C.

Increasing clouds through the day and in the low 60s with light winds.
A rotar-like cloud was evident late morning through early after noon.

Tonight's IOP was cancelled, next one not likely until Monday.

Daily Report - Wednesday March 15

IOP#4 ended at 10pm last night (6Z Mar 15) with the last sounding at 9pm.

Sunny and clear today.

Charlie backed up the MAPR-ISS data_store to DVD. I will bring this back to Boulder (backup done at 05Z Mar 15; ie 9pm Mar 14 LT)

Sounding data was not recorded for the 02 and 05 Z launches due to
a bug in the program.

Generator was serviced at Onion Valley ISS at 1 PM.

James P arrived at 1:30 and we went through bringing up the
Onion Valley ISS after the generator was serviced.

So far today:

--Brian and Heather are collecting sodar-RASS RF spectra.
--The tentative IOP beginning Wednesday night is postponed probably until Thursday night.
--Therefore we will not move MISS today. 
--Still deciding if the MISS generator service should wait until tomorrow.

Daily Report - Tuesday March 14

IOP#4 began at noon yesterday (20Z March 13) and should continue through 10 pm today (6Z Mar 15).

Quite windy at the surface, especially driving through Big Pine at 9am. Mostly SSE winds (up-valley).

MAPR froze at 21UT. Fixed at 23:45UT (1pm-3:45LT). Otherwise all data working.
Downdrafts seen most of the afternoon at ISS2 and MISS (Division Creek Rd). Some precip also, so beware interpreting vertical velocity.

Daily Report - Monday March 13

IOP#4 began at noon today (20Z March 13) and should continue through 10 pm tomorrow (6Z Mar 15).

Clear and sunny. Clouds over the Sierra peaks.

All systems operating normally.
United Rental should come Wednesday morning to service ISS2 and REAL generators.

Daily Report - Sunday March 12

No operations today. IOP#4 begins tomorrow at noon (Monday March 13, 20UT) and extend through 10pm Tuesday (Wednesday March 15 06UT)

Partly to mostly cloudy and cool but pleasant today. Heavy clouds obscuring the Sierra crest, but sunny and blue on the Inyo (east) side.Became mostly sunny by late afternoon (still clouds over the Sierra) with a full moon late in the day.

Fueled ISS2 at 1pm LT (25 gallons).
Added 25 gallons deisel to Ford transfer tank.
Fueled MISS at 01Z Mar 13 (5pm Mar 12). Tank was 1/2 full.

All systems nominal.

Took a couple of sodar-RASS spectra and maybe can transfer and email them.The spectrum looked wider than 10-kHz (centered on 915 and down 10-dB by +/- 1 MHZ, i.e. 914 and 916 MHz were down 10 dB).

Daily Report - Saturday March 11

Today was a hard down day for T-REX, but everyone was around anyway.
No operations are planned for tomorrow (Sunday). There will be a planning meeting (12pm LT) and likely IOP#4 starting monday evening (10pm LT estimate but may change).

Mostly sunny this morning. Increasing clouds by 11am (19Z) and alot of moisture apparent through the afternoon. Snow spilling over the peaks and evaporating in the valley through the afternoon, but no show reaching the surface. There mnay have been a few crystals reaching the ground on the west side (by ISFF west tower and REAL).

MISS remains running at Division Creek and was refueled about 4:30pm. Very good winds from this site. Solar shows much heavier clouds at this western site.

ISS2 also showing good winds today. It will need to be fueled tomorrow.

Daily Report - Friday March 10

IOP#3 ended at 18Z (10am) with the last sounding at 9am.All systems worked well through the IOP (except the MotoSat's sometimes would not connect).

MAPR, ISS2, and MISS all reported some 60 kt winds aloft last night (~2Z Mar 10) and many 50 kt winds above 3 km through about 6am (after which there were no sigals that high). All also showed considerable vertical motions and periods of broad spectral width.

MISS was refueled this morning, as was the ISS2 generator tank.

Daily Report - Thursday March 9

IOP#3 began at 11Z (3am) Mar 9. All systems working well.

At 00Z Mar 10: MISS still operating from Division Creek site. Spectra show vertical speeds 2-4km indicating waves. Also some snow not reaching the ground.Consensus winds are failing because of variability within the consensus period, but we'll see how NIMA does.
MISS Main tank is 3/4 full - good for another 24h, so fill by 4pm Friday (LT)

ISS2 (Onion Valley Rd) showed a very strong surface wind (17 m/s from 260) at 21-21Z today. Profiler signals look great but not consensing well.

MAPR was down from about 1-3pm LT (PC locked up). When it was brought back up, changed to wind100_rass100 mode.

MAPR appears to have some great IOP#3 data around 10UT Mar 10 (oscillations).

Daily Report - Wednesday March 8

The MISS was shut down today at about 9:50 MST (17:50 UT). It has been operating at Division Creek site since the start of IOP#2. Brian did the Kubota generator 100-hour service (oil change, etc.). We left it off until 3:30pm (23:30) when it was turned back on in anticipation of IOP#3 starting tonight. MISS will continue to operate from the Division Creek site for IOP#3.

The MotoSat links from both MAPR and ISS2 were down intermittently today. We cycled power at both sites. But it was most likely a satellite problem, not ours.

Greg McCurdy from DRI was in the valley today trying to find why the DRI surface station network is not working. We coordinated at test, turning off the sodar-RASS transmitter beginning at 1:30pm (21:30 UT). This seems to have fixed their problem receiving signals from the DRI surface network. Not sure why since sodar-RASS should be narrow band and the DRI freewaves should be able to avoid it. But we will leave it off at least for this IOP and do another on/off test when we are able.

No call back from United Rental so I'm guessing they will service the MISS-base and ISS-2 generators Monday.

Cool and breezy this morning. Clear skies all day with afternoon cirrus.

MAPR signal became weak with the collapse of the afternoon boundary layer. Changed to 200m mode at 17:30 LT (01:30 UT Mar 9).

Daily Report - Tuesday March 7

IOP2 Recap:

IOP 2 ended at 03Z (7pm last night) with the last sounding at 02Z.

During the IOP, ISS2 appears to show vertical motions and broad width between 2km and 3km AGL. But there was snow aloft which biases the vertical velocity.Winds at 3km were about 15+ m/s from the WSW for much of the IOP.

MAPR showed similar features. Downward velocity (again but there was snow), and high WSW winds aloft.

MISS was sited at the F6 location - this is the water sampler on Division Creek Rd. Its a few miles N of Independence, and west toward the Sierra. It showed a lot of vertical motions also. This is a good mountain wave case - and we'll have to see if there were rotors.

Today:
Sunny and warm this morning (10am), with fair weather Cu. By 2pm it was 8/10 overcast with ice crystals, and breezy. That may be the forecast weak front.

MISS continues to run in place at F6 (Division Creek Rd). We refueled the Kubota generator today - filled the main tank and topped off the day tank. It is due for 100-hr service tomorrow (Brian will do this) and will be down most of the day for a break. We may move to a different site in anticipation of a Thursday IOP.

United Rental asked about Hobbs numbers. They will decide if service for the MISS-base and ISS2 generators will be tomorrow or Monday to avoid the IOP.
ISS2:      2992 hrs (at noon)
MISS-base: 0219 hrs (stopped since MISS is absent)
REAL:      4490 hrs (at 2pm)

Daily Report - Monday March 6

IOP 2 Continued.

Started off cloudy and cool with occasional light drizzle,
however cleared up later.

IOP 2 is being cut short by a few hours as the situation progressed
faster than expected.  The last sounding was done at 2 UT (Mar 7).

MISS is still operating at the Division Creek Road site, and has enough
fuel to run through at least tomorrow morning.  It and the other profilers
saw some good data.  Refueled ISS2 (10G).

We did some work on the sodar, transferring the computer to a weather proof
container.  The sodar was down for a few minutes around 1 UT (Mar 7).

Backed up MAPR data (tms,cor,results,etc) up to March 7 to a USB drive to 
take back to Boulder.  Includes data_source.

Steve is taking over from Bill who is headed home.

 

Daily Report - Sun March 5

IOP 2

Partly cloudy, southerlies.
Rotor cloud band running north from about Independence close to mountians
on west side of valley, and also at times another one up the center of 
the valley further north.  Southerlies appeared to be stronger at MISS
and MAPR than ISS2.  Seeing some persistent upward vertical motion at 
MAPR and downward at ISS2 - may be trapped wave.

3 hourly sondes from MAPR starting at 17 Z (9am LT).
Leeds group are also doing soundings at airport at 1430 UT and 2330 UT
(6:30 and 15:30 LT).

MISS was moved from it's base site to site F6 (Division Creek Rd Water
Sampler) which is about 8 miles NNW from Independence.
This put it under the above rotor cloud.
The cloud drifted slowly back and forth above MISS.
We are getting a lot of clutter there but hopefully the rotor data
will make it worthwhile (and that NIMA will clean it up).

Mike and Gary's last day.  Steve and Brian are starting tomorrow.

Daily Report - Sat March 4

Clear with light southerly winds.

Systems operating okay apart from MAPR outage (see separate log entry).
Weak signal in evening so switched MAPR to 200m mode.

Finished set up of the sodar-RASS today.
It does seem to be getting a little interferencem, however it appears
to be working well and is reporting temperatures up to about 200m.  
It is sensitive to nearby metal objects; for example we shouldn't
leave a car next to it.  Otherwise it seems to operate well.
Gary set up a WiFi link to it from the ISFF trailer (about 300m) 
and it's data is being streamed back.

IOP 2 is planned for tomorrow starting at 17UT (9am) Sunday with 3 hourly
launches from MAPR.  

We also plan to move MISS to north of Independence tomorrow morning
(after the IOP starts so that we can train Steve & Brian in the move).
I scouted around a few sites - we'll probably either go to the M8 site
or the F6 site. 

Daily Report - Friday March 3

Cool, brief periods of snow or grappel, and brisk winds, partly cloudy.
There appeared to be a wave cloud (often lenticular) at south end of valley
on eastern side.  Also there seemed to be a roll cloud in the afternoon.

IOP 1 finished at 6am local this morning.  Everything seemed to go fairly well.
The last sounding at MAPR was at 3 am and had to be repeated thanks to
high winds, and also the last IOP sonde from Indy airport had to be
repeated for the same reason.

The ASU sodar went down Thursday night, but was fixed yesterday.
Apparently the electronics may have got too cold.

The ISS sodar was working from yesterday afternoon.  It reported winds
up to 20 m/s, up to heights of around 200m.  It was initally set up
such that the A1 direction set to true north, but in fact it was pointing
at 8 degrees (corrected late afternoon).

We also worked on the RASS portion of the sodar today.  
It was working from late afternoon and reporting temperatures of around 7C
(consistent with surface obs) up to around 200m.

MAPR was not writing to the RAID so the disk filled and it stopped about 21UT.
Fixed and running again from 2 UT.

Maybe having battery water troubles. Keep water heated or start early in soaking it (10min).

Signal level seems to be off for a while when starting sounding. Then it seems to come on. Cycling the rack seems to fix it or it may be related to battery voltage and colder water. 

Cycle the PC every once in a while.

Balloon bag helps.

Watch for the power lines to the north, the tower to the south and the fencing to the east.... 

Sounding rules on the wall to your left by sounding equipment.

Spare sounding equipment in the green rubbermaid.

When adjusting sounding frequencies, end them in even numbers ~ 401.78

Walk through and all systems seem fine. 

Looking through the DM and all data looks like it's coming into the workstation.
Shutting down the sounding system. Ceilometer finding a lot of clouds today! MAPR now getting a full 4+ km of data. 

Marked the empty cylinders with survey tape. 

Bit of a clean up and organizing. 

Weather has heavy clouds over the west valley side. Lighter cloud cover to the east side and blustery winds. Surface shows winds slowly increasing since midnight. 0300UT sounding shows lots of shear levels through 600mb.

Daily Report - Thursday March 2

IOP 1 underway.

All systems working well.

Mainly southerlies in valley.  
Some rotor clouds, mainly running north from Independence.
Apparent easterlies on ISS2 around 22UT and clear easterlies when 
I visited MISS 2 UT (we'll check these in post-processing).
Also possible reverse flow aloft at MAPR around 1:30 - 2 UT.

Began installing SODAR at Independence Airport about 300m north of hanger
(using the ISFF long power cable with 220V transformer).
Running winds only mode from around 1 UT (Mar 3)
(plan to work on RASS tomorrow).

Soundings going smoothly, although we're finding we need to soak the
batteries for at least 5 minutes (based on weak signal and advice from the Leeds
group who have launched lots of RS-92s).
Also it appears we should cycle the power on the sounding rack.

Daily Report - Tuesday March 1

Clear and cool with light southerly winds.

Re-orientated MISS to reduce ground clutter and generator service
on both MISS and ISS2 (see separate log entries on those systems).
Having problems with internet connection from ISS2, Gary is investigating.

IOP 1 started at 0 UT (March 2) with 3 hourly soundings from MAPR
starting at 2 UT (6pm LT).  
The IOP is scheduled to continue to 18UT March 3, with the last sonde at
17 UT March 3.
MISS is remaining at its Base Site.

We picked up the last of the sodar hardware from WMRS, the Metek engineer
will be helping us set it up tomorrow.

Daily Report - Tuesday Feb 28

Cool and clear - windy (westerlies)

The profilers got very good data during the precip, with a melting
layer about 1.7 km above the valley floor. 
MAPR showed lots of persistent vertical motion early morning
suggesting  trapped waves, and then higher frequency vertical motions
during the afternoon.

MAPR down for an hour this afternoon as Gary did some maintenance.
(Reposition computer and install DVD drives).

Upgraded GAUS software to version 2.3.1.
This version has a number of up-grades including surface station
data ingest (however this feature is not working yet).

Saw a little RFI at ISS2 - it may be from data links the ISFF group
are using at their west and south towers.

MISS profiler seeing lots of clutter in east and west beams.
We plan to reorientate it tomorrow.

The sodar arrived today at the White Mountain Research Station.

The first IOP is scheduled to begin tomorrow evening.

Daily Report - Monday Feb 27

Cooler today with brisk southerlies, lots of cloud and occasional light rain.

All systems working well.  No oblivous RFI today.

Made some adjustments to MAPR parameters, increasing the range and Nyquist
to capture more rain signal.

Continued work on processing - bird algorithm, sounding profile plots, etc.
Gary also working on getting plots into Field catalogue.
Gary also has raid configured and has transferred some data to it.

ISS-MAPR data manager rebooted at 1:51 (Feb 28) for some reason.
It happened when I blanked the Zeb display.
It seemed to recover correctly and is now working properly.

Brian visited with Eva (another student of Vanda's) - they say there may
be an IOP Thursday as the next weather system rolls in.
Weather forecast says there may be snow in the valley Friday or Saturaday.

Lou and Jason left to drive up to Reno and fly home, leaving just
Mike, Gary, & Bill.   Heather should be arriving today.

Sunday Feb 26

Set-up continued.

Brisk southerlies ahead of an approaching tough.
Cloudy - some wave clouds during morning, more widespread later.
Lots of dust blown up from Owens lake during afternoon.

Training radiosonde launched at 19 UT (see Sounding tklog entry).

In addition to sounding system, worked on MAPR (raid and bird algorithm)
plus tidying up plots etc.

TV crew filmed training launch and did tour of site.

Friday Feb 24

Fine day, clear

Mainly testing MISS today,  driving it to roving sites etc (see MISS tklog).

Briefly shutdown MAPR around 0:04 to 0:15 UT (Feb 25) to see if was causing
some RFI we were seeing at MISS - it didn't appear to be.

MAPR collecting good data.
Seeing some reflectivity layers 2 - 3 km in afternoon and evening.

Reprocessing data from early in setup with corrected wind directions.

Thursday Feb 23.  Nice sunny day.

Set-up continuing- various tidying up jobs and fixing minor bugs.

Reprocessing MAPR data for correct wind directions - seem to be consistent
with surface winds.  Also reprocessing RASS to allow ingession into Zeb.

Ceilometer hooked up to network and Gary looking at data transfer.

Arizonia State sodar-RASS set up today.  Set up on the flat above the gravel
pit beyond where the met tower is set up.  Nice looking system with multi-tone
beeps.  We're using their big wooden boxes as a wind break for balloon filling,
the only downside is that they are ASU colors.
