Subject:
SGP/MFRSR/E1 - Instrument Noise Problem
DataStreams:sgpmfrsrE1.b1, sgpmfrsrE1.a0
Description:
Intermittent spikes are evident in the data for this time period. These spikes are due to 
saturation of the instrument signal in both the diffuse and total (global) measurements 
as a result of data logger problems. The corresponding direct data can be observed to have 
an erroneous sudden drop in signal when the spikes in the diffuse and total measurement 
are observed.
Suggestions: 
Screened data before use
