SGP/SMOS/E1 - Failed temperature probe
DataStreams:sgp1440smosE1.b1, sgp1smosE1.b1, sgp30smosE1.b1
Description:
The temperature probe was out of tolerance as it failed the 6-month calibration checks and 
subsequent bi-weekly checks.  The temperature values consistently were outside the 
manufacturers suggested uncertainty of 0.2 C.
Measurements:sgp1smosE1.b1:
  • Beam 0 Temperature(temp)
  • Vapor Pressure (kiloPascals)(vap_pres)

sgp30smosE1.b1:
  • Beam 0 Temperature(temp)
  • Vapor Pressure (kiloPascals)(vap_pres)
  • Standard Deviation of Vapor Pressure(sd_vap_pres)

sgp1440smosE1.b1:
  • Time of Minimum Vapor Pressure(time_min_vap_pres)
  • Maximum Vapor Pressure(max_vap_pres)
  • Minimum Temperature(min_temp)
  • Time of Maximum Temperature(time_max_temp)
  • Minimum Vapor Pressure(min_vap_pres)
  • Maximum Temperature(max_temp)
  • Time of Maximum Vapor Pressure(time_max_vap_pres)
  • Time of Minimum Temperature(time_min_temp)

SGP/SMOS/E13 - RH sensor failure
DataStreams:sgp1440smosE13.b1, sgp1smosE13.b1, sgp30smosE13.b1
Description:
The T/RH sensor relative humidity data is suspect during this time.  Values from this 
sensor failed the 6-month check and subsequent bi-weekly checks.  The RH values were lower by 
larger than the manufacturer suggested uncertainty of 3%.
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)
  • Time of Minimum Vapor Pressure(time_min_vap_pres)
  • Maximum Relative Humidity(max_rh)
  • Time of Minimum Relative Humidity(time_min_rh)
  • Maximum Vapor Pressure(max_vap_pres)
  • Minimum Vapor Pressure(min_vap_pres)

sgp30smosE13.b1:
  • Standard Deviation of Relative Humidity(sd_rh)
  • Standard Deviation of Vapor Pressure(sd_vap_pres)
  • Vapor Pressure (kiloPascals)(vap_pres)
  • Relative humidity inside the instrument enclosure(rh)
