OLI/MFR/M1 - Shadow under tower impacting data
DataStreams:olimfr3mM1.a0
Description:
We believe a shadow from a nearby structure, "the hangar", is affecting the MFR data.  The 
suspected impact can generally be seen on clear days, e.g., 10/29, 11/02, 11/06, 11/09, 
and 11/12.  Data on overcast or mostly cloudy days are likely OK.

OLI/AMC/M1 - Data missing from loss of power
DataStreams:oliamcM1.b1

Data is missing due to logger battery voltage dropping below operational range of about 9 
VDC, and the logger shutting down automatically in order to preserve battery life.

D160330.1 was recently completed. But that DQR did not specify rearchiving the 
oliaosghgauxM1.a1 data that is created when the oliaosghgM1.a1 data is created. 

We need to re-reprocess this date and this time store the oliaosghgauxM1.a1 data in the 
Archive. 

There will be some minor changes in the oliaosghgauxM1.a1 data. When NaN values are found 
in the raw data, those values will be replaced by values of -9999.
