Description:	During the time periods specified, the SMOS.E6 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.

Subject:	SGP/SMOS/E6 - Reprocess: Incorrect wind speed calibration
DataStreams:	sgp1440smosE6.a0, sgp1smosE6.a0, sgp30smosE6.a1
Description:	EDITOR'S NOTE: A portion of the period of time to which this DQR applies is prior to the begin date of regular ARM data collection. The actual begin date of the problem described in this DQR is 951214.0000. All wind speeds reported from SMOS.E6, Towanda KS, until 3 APR 96 at 1430 GMT are too low due to an incorrect sensor calibration being used by the data logger.
