End of T-REX project

System shutdown (around 23 UT May 1) and data backup.
Profiler SPC files backed up to DVD and the data manager backed up to USB drive
(since there's too much data for DVDs).

Set ISS2 profiler into 60 meter mode for the EOPs tonight and tomorrow. 0UT.

ISS2 generator filled - 22G.

ISS2 wind profiler stalled at 0UT.
POP was showing the text of the wind consensus and had just turned on RASS.
RASS was emitting sound, but POP had stalled.
It is not obivous why the stall occurred.
Checking crontab on data manager, there isn't shouldn't be a spectral file
transfer at that time, just the usual consensus file transfer.

Note reverse flow, easterlies aloft, westerlies near ground (possible rotor)
22 UT (Apr 26) for a couple of hours.

On the 24th of April the system was shut from approx 17:45 to 18:30 for generator servicing.

From approx 23:00 on the 24 to 15:55 on the 25th the radar was hung in rass mode. The pop program was shut down and restarted. The system was observed for two rass cycles during which time everything appeared to work correctly

Took POP to setup screen (demonstrating for Jason).
Did not change modes, still in 100m mode, however on the next consensus
the data manager ingest put the 100m winds back in prof915l (low mode)
instead of prof915h as it had been doing since the last EOP.
It's not clear why this happened, but the data is still being recorded okay
so it isn't a problem.

Restarted profiler computer (training for Jason).

generator was filled @ ~2pm did not note how many gallons it took. sorry!  the main tank was at around half full.

Switched profiler from 60 m mode to 100m mode for tomorrow's IOP.
The velociy aliasing is also a little wider (17 m/s).

The POP process on the profiler PC stalled at the end of the 
23:30UT connsensus.  The display on the PC was the wind profile plot.

It's not clear what caused the stall which occurred about 40 minutes
after we left the site.  No error messages.

Wasn't responsing to keystrokes, however did respond to crtl-alt-del,
which put me back in the WinXP screen.  Rebooted to clear reset the PC.
Running okay from about 1:55 UT.

Fuel filled, 22 G

Backup RAW and NIMA data to DVDs

Switched profiler to 60 meter mode for tonight's EOP.
Similar settings to MISS (although slight differences in IPP
to reduce RFI).

Reduced delay to 1800 ns to lower first gate to 120 meters.
Produces slight spurs in spectra, but should be okay in post-processing.

Widened RASS to -10 to 30C as it may get hot tomorrow.

Daily Report - Sunday April 16

IOP 13 underway.  
Southerlies at low levels increasing through the day and occasionally
jumping around in direction - appears to be some reverse flow during 
the afternoon.
Clear skies early, then high clouds (with wave patterns) and 
ridge-top clouds forming along the Sierra often drifting part-way
over the valley.  Some snow blowing off the ridges.
Dust increasing.

All systems working well.  
The soundings show dry air aloft so the profilers aren't seeing very high.
Still some interference at ISS2 and MISS (MAPR okay) - 
suspect some of it may be the sodar-RASS.
NIMA still doing a good job of cleaning up the data.

ISS2 profiler clock appears to be about 2 minutes fast.
Don't want to interupt profiler ops during IOP so will check and fix
after IOP finishes.

Sodar working okay, however not seeing very high due to the wind.

Had four sondes with bad RH sensors, they were not launched.
See the sounding log at MAPR for details.

Deer near ISS2 this morning.

Filled generator tank - 10G  17 UT

Backed up the profiler SPC files to DVD.

Raw data backup too big for one disk so just backed up SPC files using

growisofs -R -J -Z /dev/hdc /data/ds/spc

SPC files from D06045 to H06106 3.8 GB

Still have RFI up here

There is a battery in this IR but not the MISS IR.

Fill gen with deisel

everything is restarted, no to do the mazanar site.

All radar data stopped flowing at 3 April 00z.  The profiler PC screen was
stuck on the green consensus summary profile plot.  It did not respond to
any keys.  I hit Alt-ESC to return to the Windows desktop.  When I tried to
reboot, Windows said the POP cmd.exe session would not terminate.  I forced
a reboot anyway.

On restart the K: drive did not work, but this has been a recurring problem
at this site.  I tried disconnecting and reconnecting the K: drive, but it
still did not reconnect at startup like it should.  I had to open the K:
drive shortcut and enter the password for the K: connection to work, before
the POP program started.

It appears to be working now; I'll check that the consensus makes it across
when I return to mapr.

Made DVD backup of data at 2110 UTC on March 29th

23 gallons

2115 UTC - brief period of strong easteries at the surface, dark clouds overhead
with light rain sprinkles

profiler appears to be getting good signal up to 6 km, not clear
why some much data is being removed by qc for online quicklooks
and issgp1

23 gallons

refueled generator 35 gallons Mon Mar 20 at 4 PM.

all systems functioning normally

stopped pop to copy files from yesterday at 0110 UTC.

started it back up and everything seems to be fine - (i.e., latest 
data can be viewed with the data manager computer.)

concensus winds came across to the data manager and look good
nice profile up to 2500 m

refueled generator 23 gallons Fri Mar 17 at 12 noon.

The profiler/rass has been down since 4 PM yesterday.
It appearantly hung up at 2359 UTC March 16th during a
consensus wind calculation as the x-y plots of
wind speed and direction were still displayed on the 
profiler computer screen.

As per B. Brown's direction:

The profiler software was killed and the computer was restarted.

However, on restart the link between the data manager and profiler computer
was not automatically established, so we had to manually log into the k 
drive (on datamanager).

No data was collected between 00 UTC and 1930 UTC. This was checked
before restarting the profiler software.

Moving 1 box of sondes to MAPR

Inspected equipment, O.K.
Systems appear to be operating normally,
Pumped 63 gallons of fuel into transfer tank,
Check generator, operating normally, fuel level good
Profiller disk 0.0% full
Rass operating.
Web site appears to be updating.

Added 18G (3/8)
Bill added 10G on 3/6

Plenty of RFI loading into the beams. I will be necessary to get the ISFF guys to turn off their data transmitter during one of these periods to find out if that is the source.

Site check shows things fine. 

Moving generator mag box to rear of ISS2 trailer underneath. 

RFI.

There is a little intermittant radio interfence on the north beam.
It is about 1 dB on the spectra, and does not appear to be causing
wind problems at this time.
It might be due to the sodar-RASS. 

Arrived at the site to check on satellite internet, but it appears to have corrected itself.  It's possible that the router needed to renew it's DHCP lease with the DW6000 modem, and it finally timed out, but I find no indications of what could have been the problem.  The latest data transfer at 03:10 UTC succeeded, and web browsing is working fine.

Small change to parameters to match MISS

Reduced Coh Avg slightly to widen velocity aliasing.  0:50 UT.

K Drive was disconnected for about an hour after generator service
(see previous message).

Generator Service

System shut down for about an hour from 23UT (Mar 1).
When powered back up Motsat claims to have a link,
but web browsing not working and data probably not transferring.

Had to restore K drive manually.

Profiler parameters and K Drive

Profiler paraameters:  some velocity folding (eg around 21:20UT) so 
adjusted parameters so that velocity aliasing is now 15 m/s.  
Also increased hgts to 6km.

A little occasional RFI (eg at 21:20). 
The surface group may be using data links at 900MHz that may
be causing some of the RFI.

K Drive.  Some problems with K drive not automatically connecting after
boot.  Gary rebooted prof PC several times trying to fix.
For now we need to manually connect the drive after each boot.

Gary also did work on network timer client on prof PC.

Brisk southerlies all day - seen by MAPR and MISS,
but ISS2 180 degrees out.  
Actually 175 deg out after compass recalibrated.
Fixed 23 UT.

Also altered beam sequence to N, E, S, W.

Setup finished at this site (ISS2)

Started system around 21:15 UT

Initially consensus files weren't transferring over from the profiler.
Opening explorer on the prof pc initially showed k drive on data manager
on available, but after a few seconds it opened by itself.
Consensus files now transferring okay.

Camo net install

Checking directions on profiler, they seem to be out - recheck tomorrow.
The X-37 side was set up as 116 deg, I'm reading 112 deg so that's just 4 deg.
However bearings on Manazar and radio tower are 3 or 4 deg out
as compared to a topo map.  I'm going to compare this compass
with the MAPR compass to recheck directions.

 

Net Rad domes were replaced before system was brought up at 21:15z 2-25-06

Today we have seen wind gusts up to 40 mph. Some cloud cover over the mountains, otherwise clear skies overhead. All surface sensors OK. Profiler test started.  Motosat almost up.
