Subject:	SGP/SMOS/E8 - Reprocess: Wind speed calibration
DataStreams:	sgp1smosE8.a0, sgp30smosE8.a1
Description:	EDITOR'S NOTE: The earliest portion of the period of time 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 upon request. The actual period of time covered by this DQR is 930403.0000-930811.1530. 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.

Subject:	SGP/SMOS/E8 - Reprocess: Incorrect wind directions from E8 SMOS
DataStreams:	sgp1smosE8.a0, sgp30smosE8.a1
Description:	When the Wind Monitor was changed at E8 for scheduled PM, the replacement sensor was incorrectly wired to the data logger. It did not effect the wind speed readings, but wind directions had E and W reversed. Thus winds from 15 deg were reported as being from 345 deg, and vice-versa, and winds from 165 deg were reported as being from 195 degrees, and vice-versa.

DataStreams:	sgp1smosE8.00, sgp1smosE8.a0, sgp30smosE8.a1, sgp1440smosE8.a0
Description:	Icing conditions at E8 caused the SMOS wind speed data to be questionable between 1400 and 2130 GMT on 16 MAR 98 and again between 0430 and 1630 GMT on 17 MAR 98. The data appear to be unaffected between those two periods, but may also be questionable.
