Subject:	SGP/SMOS/E4 - Incorrect Offset for Wind Directon
DataStreams:	sgp1smosE4.b1, sgp30smosE4.b1
Description:	An incorrect offset of 7 degrees was subtracted from the wind direction to correct for misalignment of the towers to true north. The wind direction data may be corrected but the vector averaged wind speed cannot. Subsequent audits have highlighted problems with past measurements of tower alignments. All corrections to wind direction are being removed and Users are directed to view the Instrument Handbook for a table listing all tower alignment deviations from true north. Users can adjust the data at their discretion.

Subject:	SGP/SMOS/E4 - Incorrect rain data from E4 SMOS
DataStreams:	sgp1smosE4.a0, sgp30smosE4.a1
Description:	The rain gauge funnel was found to be clogged during 30 OCT 97 PM. It was cleared at 1657 GMT. No clog was present during previous PM on 15 OCT 97. Date and time that clog occurred is somewhere between 15 and 30 OCT 97.

DataStreams:	sgp1smosE4.00, sgp1smosE4.a0, sgp30smosE4.a1, sgp1440smosE4.a0
Description:	Icing conditions at E4 caused the SMOS wind speed to be questionable starting at 0900 GMT on 16 MAR 98. By 2100 GMT, the icing caused the propellor to quit. The ice melted and the sensor resumed reporting wind speed at about 1530 GMT on 17 MAR 98.
