SGP/SWATS/E10 - Rain gauge failure
DataStreams:sgpswatspcpE10.b1
Description:
The swatspcp rain gauge did not report any precipitation after 04/15/09 while the closest 
Oklahoma Mesonet site at Copan, OK (20 km south of the E10 ARM site) recorded over 9 
inches of rain between April 18 and May 14.  Maintenance on 5/26 corrected the problem.
