SGP/SMOS/E9 - 6-month Calibration Checks
DataStreams:sgp1smosE9.a1, sgp1smosE9.b1, sgp30smosE9.a1, sgp30smosE9.b1, sgp1440smosE9.a1
Description:
During the time periods specified, the SMOS.E9 tower was
lowered for 6-month Calibration Checks.  During these times 
wind data are incorrect and temperature and humidity data 
may be incorrect.

Note, exact times when tower was down or maintenance was
being performed is sometimes unknown.  Users should use
the remaining data from these days with caution.

SGP/SIRS/E11 - SWFANAL Data description error
DataStreams:sgp1swfanalsirs1longE11.c1, sgp15swfanalsirs1longE11.c1
Description:
The long name attribute for the cloud effect fields incorrectly
defines the cloud effect to be the difference between the 
clearskyfit and measured values:
   
"Difference: ***fluxdn_clearskyfit - ***fluxdn_measured (***fcg)" ;
   
The cloud effects are correctly calculated by subtracting the
irradiance calculated in the clear sky fit from the measured 
irradiance.
   
"Difference: ***fluxdn_measured - ***fluxdn_clearskyfit (***fcg)" ;
   
NOTE: this is just a documentation error.  The data are correctly
calculated.
Measurements:sgp15swfanalsirs1longE11.c1:
  • Difference: difswfluxdn_measured - difswfluxdn_clearskyfit (diffcg)(difswfluxdn_cloudeffect)
  • Difference: sswfluxdn_measured - sswfluxdn_clearskyfit (sswfcg)(sswfluxdn_cloudeffect)
