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.
Measurements:sgpsurthrefC1.b1:
  • Vaisala probe 3 temperature maximum(temp_V3_max)
  • Vaisala probe 3 RH standard deviation(RH_V3_std)
  • Vaisala probe 1 temperature standard deviation(temp_V1_std)
  • Vaisala probe 1 temperature maximum(temp_V1_max)
  • Vaisala probe 3 temperature standard deviation(temp_V3_std)
  • Vaisala probe 3 RH maximum(RH_V3_max)
  • Vaisala probe 3 average RH(RH_V3_avg)
  • Vaisala probe 1 temperature minimum(temp_V1_min)
  • Vaisala probe 3 temperature minimum(temp_V3_min)
  • Vaisala probe 1 average temperature(temp_V1_avg)
  • Vaisala probe 3 average temperature(temp_V3_avg)
  • Vaisala probe 3 RH minimum(RH_V3_min)
