TWP/CSPHOT/C1 - Obstruction in collimator tubes
|DataStreams:||twpcsphotppC1.a1, twpcsphotalmC1.a1, twpcsphotaotfiltC1.a1, twpcsphotaotC1.a1|
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.
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.
