SGP/SMOS/E27 - Intermittent wind direction problems

Wind direction was intermittently sticking in the 355 degree range throughout the time 
period.

SGP/SMOS/E1 - RH high when near saturated

Instrument RH values consistently exceeded MAX and did not compare well to surrounding 
sites.  Problem was apparent only when local RH values were in excess of 90%, usually 
between 02-16Z.

SGP/SMOS/E3 - Rain Gage Data Suspect

On 06/24/2009 The rain gage tested ok.  On 07/08/2009 the rain gage failed testing.  Since 
the gage failed at some point between these dates, all data in this range should be 
viewed as suspect.
