NSA/MFRSR/C1 - No data collected during winter

The sun does not rise above the horizon at the NSA sites between November and January each 
year.  During this time period, the MFR instruments are removed and returned to PNNL for 
maintenance and calibration.  The instruments are generally re-installed in March.
