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. |
