SGP/TSI/C1 - Icing event
DataStreams:sgptsiskycoverC1.b1
Description:
An icing event (winter storm Cara) passed slowly through the area during this time frame.  
The TSI image was affected by ice accumulation on the mirror.

The TSI images were affected by an ice storm that caused the mirror to be covered with 
ice, the shadowband to stop rotating, and condensation to blur the images.

SGP/TSI/C1 - Reprocess: Corrupt properties file
DataStreams:sgptsiskycoverC1.b1
Description:
The YYYMMDDHHMMSS_tsi.properties files were corrupted when the computer operating system 
was upgraded, causing the ingest to assign incorrect values to attributes opaque_thresh, 
thin_thresh, cam_mir_dist, and center_x. A default properties file from 5/25/2004 was 
briefly used and then a properties file from 10/11/2013 was being concatenated to the current 
properties file before it was moved to the ingest directory, so that the last values 
read were from the earlier date.
