Subject:	SGP/SMOS/E6 - E6 SMOS Wind Direction
DataStreams:	sgp1smosE6.a0, sgp30smosE6.a1
Description:	Wind Direction incorrect during this time period. The bracket used to mount the wind direction sensor broke (ice suspected) on the 9th of February. It was replaced during routine maintenance on the 16th of February. We do not know why the data did not recover until the 22nd.

Description:	Wind Direction incorrect during this time period. We noticed the data was incorrect on the 28th of February. During routine maintenance on the 1st of March the technician checked the wind direction sensor and noted that it needed to be replaced (no spares on hand at the time). On the 15th of March the sensor was replaced.

Description:	All humidity data taken by SMOS E6 between 16 AUG 96 at approximately 2130+ GMT to 17 AUG 96 at approximately 1000 GMT are incorrect. The reported RH went to zero and slowly recovered. The cause is unknown.
Measurements:	sgp30smosE6.a1: sd_vap_pres Humidity, relative, 30-min intervals, standard deviation(sd_rh) Humidity, relative(rh) Pressure, vapor, 60-m height, 30-min intervals(vap_pres) sgp1smosE6.a0: Pressure, vapor, 60-m height, 30-min intervals(vap_pres) Humidity, relative(rh)
