Subject:	TWP/CSPHOT/C1 - Obstruction in collimator tubes
DataStreams:	twpcsphotalmC1.a1, twpcsphotppC1.a1, twpcsphotaotfiltC1.a1, twpcsphotaotC1.a1
Description:	During this time period, data were suspect due to obstructions in the collimator tubes. The instrument was also due for calibration.
Suggestions:	Use the quality assured level 2.0 AOT data from AERONET when available(twpcsphotaotfiltqaC1.a1). Level 2.0 data and post-calibration level 1.5 data should become available in 2014. Can also use MFRSR data if available.
