SGP/Sonde/C1 - Bad RH in sounding
DataStreams:sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
The RH sensor heating circuit was out of synch from about 400 sec after launch until the 
circuit was turned off whent he sounding temperature reached approximately 233 degK (-40 
degC) about 1500 sec after launch.  During this time period the reported RH oscillates 
between reasonable values and near-zero values.

SGP/Sonde/C1 - Sondes launched an hour early
DataStreams:sgpsondewnpnC1.00, sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
It looks like someone forgot to set his/her clock ahead.  The sounding that should have 
been done at 23:30 UTC on 4/6 was done at 22:38 and the following sounding, which should 
have been done at 0530 on 4/7 was done at 04:31.  The subsequent soundings all are done at 
the correct times.

SGP/Sonde/C1 - Incorrect surface temperature on CF sounding
DataStreams:sgpsondewnpnC1.a1, sgpsondewnpnC1.b1
Description:
It appears that the operator entered an incorrect value for surface temperature.  Rather 
than 43.2 degC in the file, the value is most likely 19. degC (thwaps reading 19.4, first 
sonde reading aloft 18.6).
