incorrect.  In many instances it was frozen and unmoving, at times it
measured values but those are extremely suspect.

A snow/ice storm moved through the SGP region on 01/31/08 bringing below-freezing 
temperatures, affecting the precip field.  Data is suspect during the date/time range specified 
due to melting ice after temperatures warmed above freezing.

SGP/SMOS/E7 - Incorrect Offset for Wind Directon

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

direction values appear to recover on the 02/10/2009 but are still suspect.  The wind 
sensor was replaced on 02/24/2009.

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.

SGP/SMOS/E7 - Humidity data drifted out of tolerance

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.
