NSA/MFRSR/C2 - 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.
