OLI/MET/M1 - Instrument problem
DataStreams:olimetM1.b1
Description:
The chilled mirror dew point, vapor pressure, and relative humidity data fall out of 
agreement with co-located sensors during this time. After an instrument self-check, the 
problem was resolved.

OLI/MET/M1 - Present weather detector backscatter warning
DataStreams:olimetM1.b1
Description:
During this time, the present weather detector intermittently indicated a backscatter 
warning. A routine lens cleaning eliminated the backscatter. Data do not appear to be 
affected.
