Subject: | 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. |

Subject: | 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. |

Subject: | 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. |
