SGP/SMOS/E9 - Reprocess: Wind speed calibrations

EDITOR'S NOTE:  The earliest portion of the period of time covered
by this DQR occurred prior to the begin data of regular ARM data.
Those data are not readily available from the ARM archive but are
available upon request.  The actual period of time covered by this
DQR is 930331.0000-930823.2359.


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.

• Wind speed, 30-min intervals, standard deviation(sd_wspd)
• Mean Wind Speed(wspd)
• Wind speed, vector-averaged, at 10-m height, 30-min intervals(wspd_va)

• Wind speed, vector-averaged, at 10-m height, 30-min intervals(wspd_va)
• Mean Wind Speed(wspd)

SGP/RL/C1 - Metadata errors
