    What location was the data collected at: SGP/CF
 
    Period of time in question
 	Begin Date  4/17/95   Time   14:29    (GMT)
 	End Date    4/17/95   Time   15:51    (GMT)

 Data should be labeled:
 ___  questionable                      ___  All data fields affected
 _X_  incorrect                         _X_  Only some data fields affected
 ___  wrong calibration
 ___  others 
 
 Discussion of Problem:

The operator entered incorrect surface values for both RH and pressure.
Because of the way altitude is calculated, the incorrect pressure value
has the effect of making all subsequent altitude values incorrect.  The
RH error only affects the first sample.  

 
Other observations/measurements impacted by this problem:



Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)

Flag data.
