SGP/MWR - MWR Scaled sondes too wet
DataStreams:sgplssondeC1.c1
Description:
As discussed in P000109.1, two of the MWR scaled radiosondes were 
scaled such that the relative humidity profiles greatly exceeded
100% RH for large fractions of the profile.  The two launches that
were affected were on 991203.0531 and 991204.0530.  In both cases,
the scale factor was on the order of 1.9.  Users should beware of
all MWR scaled radiosondes with scale factors outside the range of
0.8 - 1.2.

SGP/SONDE/C1 - Bad Temperature Sensor
DataStreams:sgpqmemwrcolC1.c1, sgplssondeC1.c1, sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
It appears that the temperature sensor broke upon launch and therefore the reported 
temperature is approximately 40 degC too low.

Description:
It appears that the temperature sensor broke shortly after launch. Temperatures are offset 
by approxmiately (but not constantly) 40 degC.

Bad temperature sensor
DataStreams:sgplssondeC1.c1, sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
It appears that the temperture sensor broke a few seconds into flight.  This results in an 
unreasonably low temperature for the rest of the flight.  For some reason, the rh values 
also go missing shortly after launch.  Only the wind and pressure data are reliable.

with the antenna configuration resulting in signal loss

SGP/SONDE/C1 - Temperature/RH incorrect
DataStreams:sgplssondeC1.c1, sgpsondewnpnC1.b1
Description:
The temperature throughout this sounding is too high and as a result the RH values will be 
incorrect as well.  I'm not sure what is wrong here but the operators noted reasonable 
values (18.1 degC, 87%) in the log before launch.  Review of the raw data, however, shows 
the sonde reporting temperatures nearly 20 degC higher.  I suppose it is possible that 
the operator entered into the log the reference temperature from the GC25 ground check set 
rather than the temperature reported by the sonde - I can't think of any other 
explanation - there is no doubt that the temperature sensor on this sonde was bad.
