 ___  others 
 
 Discussion of Problem:

The temperature values in this sounding are obviously incorrect (exceeding
60 deg C) at times.  Although the pressure and RH values are within nominal
ranges, these data too appear (qualitatively irregular).  I cannot identify
the specific cause of the problem; it is possible that the temperature
sensor on the sonde was bad, that the operator mistakenly read in the wrong
calibration tape, or that interference from a VORTEX sonde confused the
system.  

 
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.)

I suggest this entire sounding be labelled suspect and the temperature
data be labelled incorrect.
