TWP/GNDRAD/C2 - Incorrect or missing data

During the time range specified the GNDRAD datalogger and all instruments were reporting 
either missing or incorrect measurement values.  The problem resolved itself on 8/14/13 
with the shortwave, longwave and IRT instruments returning to normal readings.  

Note that on late GMT on 8/18/13 through early 8/19/13 site ops replaced the logger 
backplane resulting in several hours of missing data.  The shortwave (PSP instrument) and 
longwave(PIR instrument) upwelling data were good before and after this time.

Data are unrecoverable.
