SGP/SWATS/E13 - Reprocess: Changed Depth Dimension
DataStreams:sgpswatsE13.b1
Description:
The dimension "depth" in the netCDF files was incorrectly reported as 8, and has been 
changed. Newer files with the correct smaller depth dimension do not have extra placeholder 
values and thus are smaller in size.
Measurements:sgpswatsE13.b1:
  • depth(depth)

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)
