Subject:	SGP/SONDE/C1 - Bad RH Data
DataStreams:	sgpsondewnpnC1.b1
Description:	The RH values during the first half of this sounding oscillate between reasonable values and near-zero values. The oscillation is irregular and seems to be related to failure of the RH sensor heating process.
Measurements:	sgpsondewnpnC1.b1: Dewpoint Temperature(dp) Humidity, relative(rh)

Subject:	SGP/SONDE/C1 - Surface pressure incorrect
DataStreams:	sgpsondewnpnC1.b1
Description:	I think the operator inadvdertently transposed to digits when entering the surface pressure value. The value entered is 987.0 hPa but the value shown in the raw data file at launch is 978.0. As a result, the absolute altitudes in this sounding will be slightly incorrect as will be the ascent rate during the first 30 seconds of flight.

Subject:	SGP/SONDE/C1 - Temperature sensor broke high into the sounding
DataStreams:	sgpsondewnpnC1.b1
Description:	The temperature sensor on this radiosonde appeared to break 56 minutes and 22 seconds into the sounding at an altitude of 16570 m. All the data below this point are good; only the data above this point to the end of the sounding (88 minutes and 14 seconds) are bad.

Subject:	SGP/SONDE/C1 - Incorrect surface temperature
DataStreams:	sgpsondewnpnC1.b1
Description:	The operator entered a 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.

Subject:	SGP/SONDE/C1 - DigiCORAIII failed, replaced with S01/S02 launches
DataStreams:	sgpsondeC1.00, sgpsondewnpnC1.b1
Description:	The digiCORA-III failed on Saturday 2004-01-17. The operators reported that they were unable to load the software and conduct normal soundings. Following procedure, they conducted the regular soundings by using the S01/S02 systems as allowed by the AIRS IOP schedule. The netCDF header fields "input_source" and "facility_id" will mention which of the S01/S02 systems was used in these launches.
