Subject:
TWP/CSPHOT/C1 - Obstruction in collimator tubes
DataStreams:twpcsphotppC1.a1, twpcsphotalmC1.a1, twpcsphotaotfiltC1.a1, twpcsphotaotC1.a1
Description:
During these time periods, there were obstructions in the collimator tubes, causing 
"InGaAs/Silicon Discrepancy" errors . A wasp nest was found. The blockages caused discrepancies 
in the data between the 1640 and the other channels. The 340 and 380 channels are also 
off.
Suggestions: 
During this time period mentor recommends using the quality assured level 2.0 AOT 

data from AERONET when available (datastream name twpcsphotaotfiltqaC1.a1). Level 2.0 data 
and post-calibration level 1.5 data should become available in 2012. Can also use MFRSR 
data if available.
