DataStreams:	sgp1smosE7.b1, sgp30smosE7.b1, sgp1440smosE7.b1
Description:	The wind sensor bearings were failing causing the wind speed sensor to report lower than actual wind speeds when the winds were below 2 m/s. The wind monitor was replaced on 05/29/2007 but this failed to correct the problem. Subsequently, the site was flooded and it took some time to re-establish normal operations.

Description:	An incorrect offset of 6 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.

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 950224.0400. Incorrect Wind Speed calibration factor used at installation.

Subject:	SGP/SMOS/E7 - Questionable Humidity data
DataStreams:	sgp1smosE7.a0, sgp30smosE7.a1, sgp1440smosE7.a0
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 950224.0400. All SMOS E7 humidity data taken during this period are questionable. The sensor was replaced several times. A "good" sensor was finally installed on 17 MAY 95 at 1732 GMT.

Subject:	SGP/SMOS/E7 - Reprocess: Wind direction incorrect
DataStreams:	sgp1smosE7.a0, sgp30smosE7.a1
Description:	The 10m tower at E7 fell on 20 FEB 97 some time after 2130 GMT. It was returned to service on 13 MAR 97 at 0600 GMT, but the wind monitor was incorrectly installed resulting in wind directions being 180 deg out until it was re-oriented on 20 MAR 97 at 1600 GMT.

Subject:	SGP/SMOS/E7 - Humidity data drifted out of tolerance
DataStreams:	sgp1smosE7.a0, sgp30smosE7.a1
Description:	The humidity data reported by the Elk Falls (E7) SMOS drifted out of tolerance starting on approximately 4 OCT 96. The RH probe started reporting values exceeding 104% RH. The SMOS underwent a 6-month verification check on 13 NOV 96, but the reference RH sensor was not operating properly at the time. At the mentor's request, the T/RH probe was replaced on 4 FEB 97, but the replacement probe was not operating within specifications. Due to lack of calibrated spare probes, the bad replacement T/RH probe was not replaced until 16 APR 97.
