Subject:
SGP/SONDE/C1 - Incorrect surface temperature
DataStreams:sgpsondewnpnC1.b1
Description:
The operator entered the surface temperature incorrectly on this sounding.  The sonde data 
file shows the temperature as 33.5 degC but the operations log shows it as 3.5 degC.  
The first temperature recorded by the sonde after launch is 3.7 degC, consistent with the 
typical early morning inversion.
Suggestions: 
Discard the first 5 temperature and relative humidity measurements, subtract the 

integrated water vapor from this level from the total, or interpolate between the correct 
surface value and the 6th level recorded by the radiosonde.
