Broken cloud cover most of the day
All platforms at both sites working
Aspirator fan at Washoe still out
As always winds higher at Washoe then at trademark
At Trademark watched the 18z data transmission appeared to work , Will check with Gary. Washoe appeared to have gotten a little more snow yesterday then trademark did.
Soundings : Both soundings today had very poor recovery of gps sats. Both launches were smooth releases in under 5ms winds with at least 6 sats before launch. The only thing different that I could see was the various pockets of snow flurries in the area This is the worst I've seen during this project. All sondes have been from the same shipment.Neither sonde had solid lock below 600mb. Some outside interfrence has got to be effecting the gps here this system was used in Improve with no problems and I can't believe everything was affected in transit .

Weather cleared up during the day.
- 51: DAILY, Site trademark, Thu 14-Mar-2002 16:41:10 GMT, Daily Log 031302
Two soundings were made the first at 6:15am local.very windy at launch. Above 350mb wind speeds of 75 to 60 m/s were reported. Again lost sounding early at approx 250 mb this was due to wind slowing ascent rate and wind direction taking sounding behind mountains.
The second sounding was tracked to 50mb no problems as upper air winds had died down from earlier flight.
All systems at both sites working fine. Winds died down during the day. Clouds increased.
Late in the afternoon snow bands moved into the area for a couple of hours. These were not forecasted by the news station and as such both systems were still in the inversion mode. As thye did not last for long did not change to rain par file. Approx 2 inches of snow fell.
More helium was ordered should be delivered tomorrow.

- 34: DAILY, Site trademark, Fri 08-Mar-2002 20:19:50 GMT, Friday 08 Mar-2002 Daily Notes
Overall: A clear sunny day. No IOP but tomorrow morning we will go after
the inversion breakup (IOP #4) and tomorrow night into Sunday may be a
melting layer event as IOP #5.
TRADEMARK SITE:
Minimum temperature -9; maximum +4C, dew point -12 to -2. Winds were as high
as 8 m/s yesterday evening but less than 2 m/s most of today. Sunny and
cloudless, RASS datat to 700-1200 m. Profiler winds look quite good today.
WASHOE SITE:
Missing data overnight because of generator shutdown. Maximum temperature
today was +4C and the dew point ranged from -7 to 0C. Wind speed decreased
from 10 m/s early to less than 2 m/s later in the day. A few early clouds, but
mostly sunny. Rass to 700 m. Profiler winds light in the afternoon.
SOUNDINGS:
No launches today.
OTHER NOTES:
Washoe Lake generator ran low on fuel last night. The hand pump would not
work. United could not respond until the morning so I shut down the site
from 0715Z (1115 pm) through fixed at 1640Z (9:40am). So:
NO DATA FROM WASHOE LAKE 0715-1640Z.
Lou arrived today. So the site is his beginning Saturday.
Note that we changed from Rain mode (RNO_R2) to inversion mode
(RNO_I at Trademark and RNO_C at Washoe Lake) between 00:30 and 01:30
this afternoon (Mar 9).
- 33: DAILY, Site trademark, Fri 08-Mar-2002 20:13:31 GMT, Thursday 07 Mar-2002 Daily Notes
Overall: Winds slowing today, but still alot of snow aloft, and sometimes
reaching the ground. No soundings today. Snow drifted by aloft and the
locations of it reaching the ground was very variable.
TRADEMARK SITE:
Minimum T of +2, max of +8. Dew point -3 to +2. Winds are about 10 m/s
until 03Z and then light from 03-16Z (up to 10 m/s again after). Cloudy
with a few sporadic periods of snow. RASS coverage 700-100 m. Profiler
still in RNO_R2 mode.
WASHOE SITE:
Minimum T of 0C, and a high today of +5C. The dew point was between -4
and +2C. Moderate winds today, 4-7 m/s with some periods of 15 m/s from
the SW. Mostly cloudy all day with periods of snow reaching the surface.
Rain gauge showed alot. Can the wind vibration be tipping it? I recall
this problem at CASES99?. RASS coverate 400-700 m. Profiler has periods
of missing winds (no consensus) but alot of structure in winds measured.
SOUNDINGS:
No launches today.
OTHER NOTES:
Washoe Lake site power problem late this evening. See note fo 08 March.
- 32: DAILY, Site trademark, Fri 08-Mar-2002 19:24:52 GMT, Wednesday 06 Mar-2002 Daily Notes (IOP #3)
Overall: IOP #3 is intended to study the melting layer as the first of two
short waves traveling down the trough bring some rain/snow to the
Sierra. Soundings are scheduled for 06Z, 15Z, 18Z, 20Z, and 03Z tomorrow
relying on the NWS for 12Z and 0Z soundings. Also a good day to train teams
of students to do launches.
TRADEMARK SITE:
Minimum T of +6, max of +12. Dew point -5 to +3. Winds are about 10 m/s
from the S (SE to SW) most of the day. Cloudy, some rain. Precip showing
on the gauge 13-14Z. RASS generally 500-700 m today and alot of profiler
winds missing (lack of consensus, so see if NIMA does better).
WASHOE SITE:
Minimum T of +4, and a high today of +9C. The dew point was between -3
and +4C. Very windy most of the day, 6-12 m/s from the SW. Cloudy with
some rain, recorded as beginning at 03Z. Rass coverage 300-900 m. The
profiler nicely captures the stronge SW winds aloft.
SOUNDINGS:
A learning experience for all.
06Z (0522): trained Prof. Hallett.
15Z (1454): trained Mark and Pete. The first sonde tried, system could not
download coefficients to the rack. Tried another sonde. This one had bad
GPS (you could hear the problem from the sound). Third sonde was successful.
18Z (1740): trained Dorothea and Lupita.
21Z (2054): (final training Dorothea and Lupita. On this release, a downdraft
blew the radiosonde into the power lines. It broke free but fell in the
field to the north. Future launched with south winds will require that
we walk into that field and release on the north side of the lines.
Put up a second sonde which lost GPS in the first minutes and did not
recover, so no winds aloft.
03Z (0216 March 7): final training fro Mark and Pete. Interesting feature in
this sounding. The sonde vertical velocity went negative several times
in the stratosphere, suggesting it was going through a large amplitude
vertically propagating gravity wave.
Overall we went through three extra/failed sondes. But did get good data for
all scheduled times and did train two teams for future launches.
OTHER NOTES:
Profiler still in RNO_R2 (rain) mode at both sites.
I think the profiler caught a few periods of melting layer structure,
mostly around 9 pm LT (5Z, and after the last 03Z sounding). Next expected
IOP will be Saturday night or Sunday.
- 25: DAILY, Site trademark, Tue 05-Mar-2002 16:42:13 GMT, Tuesday 05 Mar-2002 Daily Notes
Overall: Clouds building a little today. We replaced the anemometer
at Washoe Lake and also got communications working there with a cell
connection rather than the Freewave to the Park HQ. First launch of IOP3
will happen later tonight at 6Z (0515 launch) on March 06.
TRADEMARK SITE:
Minimum T of -4, max of +16. Dew point -12 to -5. Winds pretty calm,
increasing to 10 m/s from the SW after 20Z. Some clouds, thicker
cirrus and some wave clouds. RASS to 800 m with an inversion last night,
Profiler winds good to 1500-2000 m.
WASHOE SITE:
Minimum T of +6 (warm overnight!), and a high today of 14C. The dew point
varied from -13 to -4C. Winds calm for much of the day but some windy
periods. Wave clouds (less cloud cover than at Trademark this morning)
and a lot of high clouds. RASS to 300-500 m, Many missing profiler
winds (did not find a consensus?).
OTHER NOTES:
PROFILER MODE CHANGE: Changed Washoe Lake profiler to RNO_R2 mode at 2320 Z
Changed Trademark Drive profiler to RNO_R2 at 0000 Z (6 Mar).
Par file RNO_R2 is a rain mode whthout ICRA so I can sample with
60 m resolution to 5 km. Wide Nyquist, 50% vertical beams. 60 min cns.
Profiler PC crashed (related to using impact drill?) losing SPC file
so no SPC data from 00-0730Z (March 5, DAY 056). There should still
be SOAP moments available.
Replaced wind head at Washoe Lake at 2230 Z (a lot of help from Greg
McCurdy). The wind directions problem has not recurred today.
Worked with Gary to start data transmission through the cell phone
modem . This too is now working and seems to be solid since we
started up at 2100Z. I transferred to hast 2 days of data back to
Boulder.
The differences in wind and temperature overnight between Trademark and
Washoe Lake could be interesting to study.
- 23: DAILY, Site trademark, Mon 04-Mar-2002 17:18:58 GMT, Monday 04 Mar-2002 Daily Notes
Overall: Today we set up the DRI met tower. This is not an ISS system but
should provide interesting data. Winds were set up at 3 levels, temperature
at three levels (not the same) and there is one level with a humidity sensor.
Thicker cirrus this morning.
Weather:
Clear again today with thicker cirrus, especially in the morning. Winds were
generally light, with a few short "bursts" seen at the Washoe Lake site.
Trademark: min temperature last night was -8, and max today was +15C.
Dew point was between -9 and -12C. Winds were light, less than
4 m/s through the day. RASS measurements to 700-900 m and
profiler winds sometimes to 1500 m and to over 2000 m for a few
hours.
Washoe: minimum temperature of -5C; maximum of _13C and dew point between
-13 and -7C. Surface winds were light, but bursts at 1430-1730 and
from 2100 to 2400. RASS to 500-1000m parts of the day and profiler
winds sometimes to 1500 m
OTHER NOTES:
Moved flagging to protect DRI met tower.
- 22: DAILY, Site trademark, Mon 04-Mar-2002 17:09:20 GMT, Sunday 03-Mar-2002 Daily Notes IOP #2 (ends)
GENERAL: We finished IOP #2 with an overnight sounding. Then it became
a day for equipment repairs and failures. Clear and sunny with another
pretty good inversion.
Launches at 0Z, 12Z (March 3) yesterday evening and overnight.
WASHOE SITE SPECIFIC:
The generator was shut down for service at 17Z. At that time the UPS
did not keep power to the CPU's. When the generator was restarted the UPS
alarmed. So the CPU power strip was plugged into wall power (until this
afternoon, see note further in this entry). The CPU's are in wall circuit #3
and the monitors were moved to circuit #7. In the afternoon at 0130Z I shut
down all systems and routed the CPU's through the small UPS (IPM?) to be
used just for power conditioning.
Because of hard shut down at 17Z we lost the profiler SPC file. Should
still have SOAP moments.
TRADEMARK DRIVE WEATHER: minimum temperature -10C last night; maximum +12 and
the dew point was around -12. Surface winds were up to 6 m/s yesterday
afternoon but were below 3 m/s for all of today. Profiler winds to 1300 m
and RASS to 600-800 m.
WASHOE LAKE WEATHER: min temperature was -6C, max was +10, dew point about
-13 today. Surface wind speeds reached 6 m/s part of the day. No clouds all
day. Rass measurements to 600 m, and profiler winds to about 1 km.
OTHER NOTES:
Lost profiler SPC file 0000-1730 Z as noted above.
Installed replacement JAZ on profiler PC. Works fine, but AutoRun not working.
Noticed wind direction intermittant failure. See log entry on Surface Met,
At 17Z, people are flying a remote controlled glider near the
ISS. I did not see any extra clutter in the profiler though.
- 15: DAILY, Site trademark, Sat 02-Mar-2002 00:52:39 GMT, Saturday 02-Mar-2002 Daily Notes IOP #2 (begins)
Overall:
IOP #2 merges with IOP #1. Soundings continue (last of IOP #1 was yesterday
afternoon at 0Z Mar 02), with launches at 12Z last night, 0Z (Mar 3) this
afternoon at a final sonde will be overnight at 12Z (Mar 3).
Weather:
Clear again today with a few cirrus in the early afternoon. Winds were
nearly calm overnight, abd about 2 m/s during much of the day.
Trademark: min temperature last night was -10, and max today was +12C.
Dew point was typically -15C. Winds were light overnight
and increased to about 2 m/s during the day. Very weak
profiler signal today, with just a few winds aloft in the afternoon.
Maybe NIMA will recover more winds.
Washoe: min -7C max +6; dew point around -14 (so much colder than Trademark).
light winds at the surface all day, no clouds. RASS measured to
about 500-700 m; profiler winds to 600-1200m.
OTHER NOTES:
Replaced surface met aspirator fan this afternoon (00:30 Z Mar 3).
Also see log entry describing GLASS GPS loss of winds on some flights.
- 9: DAILY, Site trademark, Fri 01-Mar-2002 11:40:55 GMT, Friday 01-Mar-2002 Daily Notes IOP #1
Overall:
IOP today with 5 sonde launches (0Z, 6Z, 12Z, 18Z, 0Z). The IOP caught
the end of yesterday's dust storm (PV max), and the subsequent 24 hours.
If there was much of an inversion it would be completely fresh after the
strong winds.
Weather:
Clear today with some cirrus in the afternoon. Winds decreased last evening
and were light overnight. Picked up again during the day.
Trademark: min temperature last night was -9, and max today was +10C.
Dew point was -8C early, and dried further to -17 (very dry).
Profiler winds (a lot of clutter) showed a turn fron Easterky
to Southerly early this morning.
Washoe: min T was -8; max T was +4; dew point of -10 before 16Z and falling
steadily to -20 by 24Z. The peak of the wind storm was yesterday
afternoon around 03 Z with surface winds greater than 10 m/s, later
winds were less than 3 m/s. Radiation shows very clear with just
a little afternoon cirrus. Profiler winds were weak and easterly
with coverage to 1 km (weak signal). RASS to 500 m.
OTHER NOTES:
Rebooted the SUN twice at Trademark around 1950 to get comms working. Needed
the second kick to get Campbell data. Comms worked for a short time and then
stopped again. Did not ingest profiler moments again until 0015Z
Also rebooted twice at Washoe. This did not fix comms problem. I need to
swap the old, slow modem back in later.
- 5: DAILY, Site trademark, Thu 28-Feb-2002 22:08:10 GMT, Thursday 28-Feb-2002 Daily Notes
Overall:
The winds were calm overnight but increased steadily during the day. A
short wave (potential vorticity maxima) came in from the north bringing
the wind and a dust storm. Six car accident on 395 this evening (early
on Mar 01 UT) blamed on visibility.
Began IOP with sonde launches at 3:15 pm local. Described in tomorrow's
log entry.
Weather:
Clear today. Winds increased beginning at 17Z to a maximum of about 10 m/s
late afternoon (2Z). Minimum temperature last night was -7C and todays high
was +14C. JH says there was a shallow inversion seen from DRI this morning.
I saw diffuse haze without a defined top at 18Z.
Trademark: min temperature last night was -7, and max today was +14C.
Dew point was -8C early, and dried further to -13 as the
wind from the north swept in. Winds were light overnight
and increased to about 10 m/s by afternoon.
Many profiler winds were bad - no signal in the dry air. With
sporadic good winds.
Washoe: min T -5C, max T +13, dew point between -7 and -10 today. Surface winds
were less than 2 m/s early, rising steadily to 10 m/s between 18 Z and
24Z. No cirrus today. RASS coverage to 700 m.
OTHER NOTES:
Installed board to solidify first step in stairs to trailer at Trademark.
Modified aspirator with GPS slot.
- 4: DAILY, Site trademark, Wed 27-Feb-2002 17:20:20 GMT, Wednesday 27-Feb-2002 Daily Notes
Overall:
Good inversion day, but spend working with Boulder on software issues.
No soundings today.
Weather:
Cirrus all day, but less after 23Z (3pm). Inversion this morning 16Z seen from
DRI was thicker than Rattlesnake peak by about 20%. Broke up later in the
day (based on visuals of haze). Some construction activity this morning.
Bruce (site construction supervisor) stopped by for a tour of the site.
Trademark: min temperature last night was -6, and max today was +15C.
winds were light, mostly less than 2 m/s. with variable direction.
dew point around -5C. (all just like yesterday).
Profiler winds light, with a lot of clutter overnight
below 500 m. At night signal is very very weak and POP is picking
up the spurs. NIMA should shine here. Direction at 1 km rotates
from NW to NE to E to SE to E.
Washoe: min T was -3C, max +12C, dew point -4C overnight and drying to
-10C for part of the day. Sfc wind about 1 m/s from the SW (variable)
until 17Z, and then 3-5 m/s steady from the SW. Profiler winds
at 1 km begin from the N and rotate from the E. RASS to around 800 m.
Profiler shows circulation Northerly to Easterly shift (at 1 km).
Three students visited for a short time this afternoon. They will be back to
demo the first launch tomorrow afternoon.
OTHER NOTES:
Added flags to many tie-downs at Trademark. Still need to bring reflectors
from Washoe.
Replaced the modem at Washoe Park HQ. Comms there seem ok (still - apparently
they started working correctly with the other modem, too).
Fueled the generator at 20Z, it was down to 1/4 of the main tank. United
visited to fix the hand pump. Appt to shut down/service generator at
9am Sunday.
Comms at Trademark are now suspect. They work well sometimes but other times
the link is broken mid-stream.
- 3: DAILY, Site trademark, Tue 26-Feb-2002 18:51:58 GMT, Tuesday 26-Feb-2002 Daily Notes
Overall:
1. I plan to use this TKLOG (at Trademark) for daily notes applicable to
both sites.
2. Visual observation of inversions is by the depth of apparent pollution
in the air against tall buildings (Hilton) or Rattlesnake Peak or
the surrounding mountains.
3. NOTE: Profiler beam directions were not correct during Monday test
sonde. Fixed later Monday morning.
DAILY NOTES:
First day of operations. Both sites collecting data, but several problems
with plots and comms to work out.
Summary: Inversion day, no soundings, construction (pouring concrete) this
morning, but not too much activity.
Weather:
Cool overnight, cirrus this morning with an inversion seen at 7am which
appears to have been broken up at 11am observation. Cirrus all day, as seen
also in solar. Dip at 23:30 is when sun went behind a thin wave cloud.
Trademark: min temperature last night was -6, and max today was +14C.
winds were light, mostly less than 1 m/s. with variable direction.
dew point around -5C.
Profiler winds light below about 800 m, with clutter overnight
below 500 m. Looks like spurs; maybe NIMA will clean it up. But
why only at night. I need to come by late and check it out.
Washoe: min temperature -3C, max +11, dew point was 6C most of the day.
Surface winds from the WNW (1-6 m/s), except from S at 4 m/s between
6Z and 16Z. RASS measured to 700-800 m. Profiler winds light, seen
to above 1 km. At 1km they shift: from E early, from W later in day.
Max profiler wind about 7 m/s at 800 m at 20Z.
SODAR: Winds very light, measured up to 200-250 m.
NOTES:
First 2pm planning meeting today: Forecast is for high pressure and inversions
for the next many days, We plan soundings at 0Z, 6Z, 12Z, 18Z on Thursday night
and Friday (29 Feb). Students will be here for 0Z (Thursday afternoon).
