SGP/SONDE/B1 - Temperature sensor failed
DataStreams:sgpsondewnpnB1.b1
Description:
It appears that the temperature sensor on this sonde broke shortly after launch with the 
effect that the temperatures read approximately 30 degC too low.  Other measurements that 
do not rely on the temperature, for example pressure and wind velocity, should be OK.
Measurements:sgpsondewnpnB1.b1:
  • Dry Bulb Temperature(tdry)
  • Temperature, dewpoint, at altitude(dp)
  • Humidity, relative, on hybrid-b grid, derived from RUC model(rh)

SGP/SURTHREF/C1 - Instrument failure on Vaisala probe 1 and probe 3.
DataStreams:sgpsurthrefC1.b1
Description:
For the dates: 11/01/2005 - 12/01/2005 T/RH probe Vaisala #3 failed.  RH data was missing 
and the temp data wass higher than other probes.  Corrosion on the connectors caused the 
problem.

For the dates: 12/03/05 - 12/12/2005 T/RH probe Vaisala #1 Temperatures were lower than 
other sensors and intermittently failed.  A loose wire was found and corrected.

SGP/SURTHREF/C1 - Sensors out of calibration
DataStreams:sgpsurthrefC1.b1
Description:
In Nov. 2011, RH values were noticed to be out of agreement with each other. It was found 
that the sensors had not been through annual calibrations (some had not been calibrated 
since 2008). Beginning Dec. 2011, sensors were swapped and calibrated as needed. As of 
7/2/2012, all 6 sensors are up to date on calibrations.  

V2 replaced 12/12/2011. V1/V3/R2 replaced as of 01/24/2011. R1 replaced 4/23/2012. R3 
replaced 7/3/2012.
