Subject:	SGP/SMOS/E13 - 6-month Calibration Checks
DataStreams:	sgp1smosE13.a0, sgp30smosE13.a1, sgp1440smosE13.a0
Description:	During the time periods specified, the SMOS.E13 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.

DataStreams:	sgp1smosE15.a0, sgp30smosE15.a1, sgp1440smosE13.a0
Description:	The values of humidity data taken by SMOS E15 started to drift downwards starting on approximately 17 MAY 96 and continued to drift downwards until the probe was replace on 15 AUG 96 at 1630 GMT.
Measurements:	sgp30smosE15.a1: Pressure, vapor, 60-m height, 30-min intervals(vap_pres) Humidity, relative(rh) sd_vap_pres Humidity, relative, 30-min intervals, standard deviation(sd_rh) sgp1440smosE13.a0: Humidity, relative, at 60-m height, 24-hr maximum(max_rh) Time of Maximum Relative Humidity(time_max_rh) Time of Maximum Vapor Pressure(time_max_vap_pres) Time of Minimum Vapor Pressure(time_min_vap_pres) Humidity, relative, at 60-m height, 24-hr minimum(min_rh) Time of Relative Humidity(time_min_rh) Pressure, vapor, at 60-m height, 24-hr minimum(min_vap_pres) Pressure, vapor, at 60-m height, 24-hr maximum(max_vap_pres) sgp1smosE15.a0: Humidity, relative(rh) Pressure, vapor, 60-m height, 30-min intervals(vap_pres)

Subject:	SGP/SMOS/E13 - Questionable data
DataStreams:	sgp1smosE13.a0, sgp30smosE13.a1, sgp1440smosE13.a0
Description:	The values of relative humidity reported by the SMOS at E13 between 18 NOV 96 and 1930 GMT on 30 JAN 97 are too high. Saturation values of 104% to 105% have been reported during this period. A 6-month Verification Check was made on 18 NOV 96 and the SMOS probe did not agree with the reference at that time. The SMOS probe was finally replaced on 30 JAN 97. Data reported since that time appears reasonable.

DataStreams:	sgp1smosE13.a0, sgp30smosE13.a1, sgp1440smosE13.a0
Description:	When the SMOS E13 T/RH probe was replaced on 30 JAN 97, it was not adequately sealed to prevent rain infiltration. During a rain, which fell between 20 FEB 97 at 0730 GMT and 22 FEB 97 at 1230 GMT, the RH probe malfunctioned apparently due to becoming wet.
