NSA/SEBS/E10 - Tower Failure, Data Not Affected

The tripod tower top holding the net radiometer broke and collapsed.

However, at this time of year radiation is so small that effects on the radiation and 
therefore net radiation measurements can not be detected.

Therefore this DQR has been designated as transparent.

NSA/ECOR/E10 - CO2 and H2O Fluxes Missing

The CO2/H2O sensor head cable was disconnected when the ECOR tripod failure occurred on 
12/22/2012.  The problem was rectified by plugging in the cable and cleaning the LI-7500 
sensor head windows.
