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.
