Subject:
TWP/SONDE/C2 - Surface Temperature Incorrect
DataStreams:twpsondewnpnC2.b1
Description:
The first two temperature values in the datafile are incorrect.  It appears that the 
observer mis-typed the surface temperature as -27 instead of +27.  The next value was 8 which 
is also incorrect and was caused by the system interpolating from the incorrect surface 
value and what the sonde temperature sensor was reading.
Measurements:twpsondewnpnC2.b1:
  • Dry bulb temperature(tdry)
