SGP/SMOS/E13 - T/RH sensor failure
DataStreams:sgp1440smosE13.b1, sgp1smosE13.b1, sgp30smosE13.b1
Description:
The T/RH sensor began to fail at high RH% values.  Since this site has an aspirated 
radiation shield, values in excess of the 104% manufacturer limit are not expected to occur due 
to rain or condensation.
Measurements:sgp1440smosE13.b1:
  • Time of Maximum Relative Humidity(time_max_rh)
  • Time of Maximum Vapor Pressure(time_max_vap_pres)
  • Minimum Relative Humidity(min_rh)

SGP/SMOS/E27 - Reprocess: Wind direction offset
DataStreams:sgp1smosE27.b1, sgp30smosE27.b1
Description:
When the SGP.E27 SMOS tower was installed it was not aligned
properly resulting in a 7 degree offset.

  • Unit Vector Wind Direction(wdir)

SGP/SMOS/E6 - SMOS Wind direction low
DataStreams:sgp1smosE6.b1, sgp30smosE6.b1
Description:
The wind direction reported by the SMOS went from being 7 degrees too low at the beginning 
of 2005 (the 7 degrees is a result of misalignment of the SMOS tower by 7 degrees) to 
15-20 degrees too small by November 2005.

The wind sensor was replaced, bringing the wind direction back to being 7
degrees too small.

SGP/SMOS/E3 - Incorrect Offset for Wind Directon
DataStreams:sgp1smosE3.b1, sgp30smosE3.b1
Description:
An incorrect offset of 7 degrees was subtracted from the wind direction to correct for 
misalignment of the towers to true north. The wind direction data may be corrected but the 
vector averaged wind speed cannot. Subsequent audits have highlighted problems with past 
measurements of tower alignments.  All corrections to wind direction are being removed and 
Users are directed to view the Instrument Handbook for a table listing all tower 
alignment deviations from true north.  Users can adjust the data at their discretion.

  • Unit Vector Wind Direction(wdir)
  • Wind Speed (vector averaged)(wspd_va)
