SGP/SMOS/E3 - E3 SMOS WIND DATA INCORRECT

Wind speed data began to be reported as 0 m/s on 05/01/2003 @ 04:59 GMT.  The wind 
direction data became incorrect soon after the wind speed data.  It was found that the wiring 
had been broken.  The data wires were re-routed and repaired.

SGP/SMOS/E20 -  E20 WIND DIRECTION DATA INCORRECT

Wind direction data was approximately 100 degrees different from other sites and a 
co-located EBBR site.  A faulty wiring panel was the cause.

SGP/SMOS/E27 - Instrument problem, Sensor failure

The SMOS wind sensor at E27 was reporting good wind
direction for 0 and 180 degrees, but bad wind directions 
for 090 and 270 degree (sensor problem).  This problem
was noted during the SMOS 6 month calibration check on
2003-05-15.  Sensor replacement and wiring changes
cleared the problem.

The atmospheric pressure values were reported as -9999.  Reason unknown.

SGP/SMOS/E13 - Sensor failure

Beginning around 1415 UTC on 08/30, the RH readings for
this instrument were frequently around 0 (sometimes
there are erratic spikes upward from 0 for periods of
time). Rainfall appears to have been the cause of the
erroneous readings, as the instrument appeared to fail
in and around the time of heavy rains.

A maintenance visit occurred on 09/04, afterwards data
returned to normal values.
