SERIAL # B1354131
Some high cloud winds have died down.

IOP7 Sounding 6, launched at 0300 LST, Oct 31. Had to hit Bad Sonde twice during the sonde preparation to proceed (although the Lock light was green). Good sounding, burst around 28.5 mb. 

Serial # B1334523
Clear sky windy cooling

Serial # B1324145
Very windy.Hazy warM
Good flight

Serial # B1334513
Some highy cloud.
Good sounding, burst at about 26mb.

200g balloon launched 29 October at 0600 LST. Light surface winds, down to 3m/s.

IOP6 sounding 5 lauched at 0300LST. 
Near surface with strong temperature inversion.
Balloon burst approx 56mb.

200g balloon launched at 000 LST 29 October.

Sound launched on 28 October at 21 LST. GPS at first did not lock so we re-initialized the sonde and GPS locked the second time through, balloon was launched 4 min after the hour. 

Balloon burst at 36mb. Good Sounding.

Serial # B1324143. Launched at 28 October at 18 LST. Good Sounding. Balloon 
burst at 36mb.

Serial # B1324141
High clouds, light winds.
Good sounding burst approx 35mb.

IOP5 SOunding 7, launched at 0900 LST, 23 Oct.  Good sounding

IOP5 Sounding 6. Launched at 600 LST on 23 Oct. Balloon burst at 755 LST around 28mb. Good sounding with light winds.

IOP 5 Sounding 5, Launched at 0309 LST, 9 minute after the scheduled time. The previous sonde's GPS failed to lock despite that the 'Lock' light was green. This happened several times in the past and each time the problem disappeared after click on "Bad Sonde", but this time, it did not fixed the problem after three tries. A new sonde was then used with the already activated battery and the sounding went fine. 

IOP5 Sounding 4, launched at 0000 LST, 23 Oct. Good sounding. 

IOP5 Sounding 3. Launched at 2100 LST, 22 Oct.  600 gram balloon. Burst at 2240 LST at 34 mb. Good sounding.

IOP5 Sounding 2, launched at 1800 LST, 22 Oct. Good Sounding.

First sonde of IOP5 number B1534262. Launched at 2200UTC. Weak telemetry at ~600mb for a few moments during flight. Regained strength and continued on.

IOP4 Sounding 6 launched at 0600 LST, 21,, Oct.  Good sounding.

IOP4 Sounding 6, launched at 0300 LST.  Good sounding

This is the make up sounding for the 0000 LST, 21 OCT sounding. Launched at 0025 LST. Good sounding. 

IOP4 Sounding 4, launched at 0000 LST, Oct. 21. When ready to fill the balloon, noticed that the helium cylinder is leaking heavily. After several attempts, finally filled the balloon, but in a hurry to catch the time lost, forgot to close the sonde and the battery case, and the battery fall at the launch. Selected "No Sounding" for this launch, and started over again.

IOP3 Sounding 3, launched at 2100 LST. 600 g balloon. A bit wind since stronger wind aloft (~15 m/s weaterly) are begining to mix down to the surface

Sounding 2 launched at 6pm lst. B1534259 good sounding

IOP4 sounding 1 is B1534261. Winds have moved to more out of the east. Launch at 2200 UTC

IOP3 Sounding 7, Launched at 0900 LST. 

Souding 2 from IOP3 is underway. No problems. Winds are still out of the north @around 5mps. sonde ID B1544113 Launched at 404mhz

First sounding of IOP3 @ 2200 UTC Sonde ID B1534639. Winds are were strong out of the north now becoming calm. Could not recieve signal at 400mhz. Several other "spikes" are in that spectrum. Launched at 404mhz

Launched third sounding of IOP2 at 2100 LST.  Some data near surface was lost because sonde was launched before GAUS software was completed.  Sharon contacted Dave and he said it was not necessary to perform another launch. Conditions are calm and wind is light.  Sonde ID is A4530138.

Launched second sounding of IOP2 at 1800. Calm, clear conditions. Sonde ID A4530131. Ground check system acted up, see earlier entry.

Launched first sonde of IOP2 at 1500 LST. Sonde ID is Z5040054. Weather conditions are calm and clear. 

Two soundings had failure of launch detect during IOP1. D20061008_025954 was changed to D20061008_011519 and D20061008_052804 was changed to D20061008_035410.  The new filenames reflect time closer to actual launch.  LAU time in the file was also changed, as was the launch time indicated in the tail.  Data between the surface, that had not been saved in the previous D_P.1 files, was restored. 

Test launch was performed.  Strong winds, about ~7.5 m/s, scattered clouds.  Sonde ID = Z5040050

The were a couple of issues with soundings for IOP 1.

1) GPS lock problem.  This appeared to be a software problem.
On a few soundings on the "Preview Radiosonde Data" screen, the wind
fields were red indicating on GPS lock on the sonde (the GPS reference
was okay).  "Bad Sonde" was then selected (taking us back to the 
"Prepare an RS-92 Radiosonde" screen) at which point the same sonde was 
immediately reused and this time the GPS was okay.
It was not a matter of not waiting long enough or moving the sonde around.

The sondes were then launched and the data appeared to come in correctly.
However on some of these sondes the D*_P.1 files had almost no data
(producing netcdf and skew-t files with no data).
Fortunately the D*.1 files appear to be okay so the soundings can be
recovered.

2) Transfer issue.  The sounding files were not transferred across to
the data manager computer (and thus to the web).
Crontab on the data manager appeared to show a transfer job, and on the
sounding PC windows task manager showed an rsync client running.
Rebooting the sounding PC did not help.
Manaully transferred the data by opening the samba mounted k drive.

IOP 1 - Sounding 2  1UT. 

Could not get GPS signals initially. Launched it anyway. 
Clicked on Bad Sounding to get back to prev screen, then restarted
from there, which fixed the problem.  May be a software problem.
Missed first kilometre or so of sounding.

Sonde Number: B1544097
Winds decreasing, clear skies.

Operators Bill, Sharon and Wen.
 

IOP 1 - Sounding 1

Launched: 22:03 UT
Sonde number: B1534634
Weather: breezy southerly with scattered Cu

Missed burst as had to work on sodar.
32 cu ft Helium.
Good flight!

Training sounding 23 UT with 600g balloon.
Used 40 cu.ft. He since it was breezy.  Rise rate in trop was 2 - 3 m/s.

Serial number B1534627

GPS did not lock until 700mb.
Terminated at 300mb.

Operators:

Wenqing Yao
Leigh Jones
Maura Hahnenberger
Christy Wall
Crosby Savage

Sounding system test
Sonde number B1534631

Good flight - rather dry.  Winds agree with wind profiler.
Gary make a small change to ASPEN to allow sounding to go to the GTS.
