SGP/SMOS/E20 - Reprocess: Wind speed calibrations
DataStreams:sgp1smosE20.a0, sgp30smosE20.a1
Description:
EDITOR'S NOTE:  The earliest portion of the time period covered
by this DQR occurred prior to the begin date of regular ARM data.
Those data are not readily available from the ARM Archive but are
available by special request.  The actual period of time covered
by this DQR is 930403-930819.1430.


Practically all of the information in this DQR is derived from
P930723.1 and C930830.1, both of which were submitted by Dick Hart. 

The calibrations initially used for wind speeds on SMOS systems at 
Coldwater (E8), Ashton (E9), the central faciality (E13), Ringwood (E15),
and Meeker (E20) were originally "generic"values, but analysis of the 
N.I.S.T traceable calibration data reveals that use of these "generic" 
calibrations produces data with insufficient accuracy. The calibrations 
for the wind speed sensor associated with the instrument must be used 
in the datalogger program in order to obtain data with a 1% uncertainty.
For the worst case, one wind speed sensor underestimates the wind speed 
by 1.1 m/s at 30 m/s when the "generic" calibration is used.  This is 
on top of the 1% calibration uncertainty.  

No unreported data loss occurred as a result of this calibration question, 
but users of the data should adjust the wind speed values before analysis 
involving these wind speed values.
Measurements:sgp1smosE20.a0:
  • Mean Wind Speed(wspd)
  • Wind Speed (vector averaged)(wspd_va)

sgp30smosE20.a1:
  • Wind Speed (vector averaged)(wspd_va)
  • Standard Deviation of Wind Speed(sd_wspd)
  • Mean Wind Speed(wspd)

SGP/SMOS/E9 - Bad Humidity Data
DataStreams:sgp1440smosE9.a0, sgp1smosE9.a0, sgp30smosE9.a1
Description:
During a rain storm the relative humidity readings (and vapor pressure
which is derived from RH) became erroneous.  The sensor electronics may
have gotten wet.  The sensor recovered from whatever problem occurred
e.g., the sensor dried out).  No permanent damage occurred.

No other measurements appear to have been affected.  Temperature
measurements during the period in question, agree with those obtained
by the EBBR.
