Platform/Measurement:
What level data: (raw,a0,a1,b1,c1 etc):raw, a0, a1, et seq.
What location was the data collected at: SGP/BF4 (Vici)
Period of time in question
Begin Date 8/ 7/94 Time 05:30 (GMT)
End Date 8/ 7/94 Time 07:15 (GMT)
Data should be labeled:
___ questionable _X_ All data fields affected
_X_ incorrect ___ Only some data fields affected
___ wrong calibration
___ others
Discussion of Problem:
The temperature, RH, and (likely) pressure data for this sounding look
incorrect. The temperature after launch is much too high, the RH drops
almost immediately to near zero, and the reported height of the sounding
is much greater than would be expected. Most likely cause is operator
error (using the wrong calibration tape).
Other observations/measurements impacted by this problem:
Anything that uses sounding data. Even the winds are probably reported
at the wrong altitudes (pressure problem).
Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
There is no way to fix the data. The sounding should be deleted or
flagged as bad.
