Subject:	TWP/CSPHOT/C1 - Filter degradation
DataStreams:	twpcsphotppC1.a1, twpcsphotalmC1.a1, twpcsphotaotfiltC1.a1, twpcsphotaotC1.a1
Description:	Channels 340,380 and 1640 are in disagreement with the other channels, possibly due to degradation of filters or a problem with the InGaAs detector. There were also "InGaAs/Silicon Discrepancy" errors reported during this time.
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
