SGP/SMOS/E6 - Wind Data Incorrect Due to Icing
DataStreams:sgp1440smosE6.b1, sgp1smosE6.b1, sgp30smosE6.b1
Description:
An ice storm caused the wind data from the RM Young wind sensor to be incorrect.  In many 
instances it was frozen and unmoving, at times it measured values but those are extremely 
suspect.

Description:
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/E6 - Incorrect Offset for Wind Directon
DataStreams:sgp1smosE6.b1, sgp30smosE6.b1
Description:
An incorrect offset of 7 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.

  • Unit Vector Wind Direction(wdir)
