SGP/TSI/C1 - Ice storm

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.

NSA/TSI/C1 - frost on lens

The camera lens window was covered with frost because the thermal pad in camera housing 
was not powered on.

NSA/TSI/C1 - Condensation on lens

The images and fractional sky cover values are affected by moisture inside the camera 
housing. The desiccant was added.

ENA/C1 - Reprocess: Slightly incorrect location fields

Some of the instruments are being processed with the previous "GRW-Azores" lat/lon/alt 
instead of the new "ENA-Azores" lat/lon/alt. The differences are minor, but will be 
corrected. The respective GRW and ENA lat, lon, and alt values are as follows:
 
GRW  lat = 39.0911 ;
ENA lat = 39.0916 ;
GRW  lon = -28.0297 ;
ENA  lon = -28.0257 ;
GRW  alt = 26 ;
ENA  alt = 30.48 ;

AWR/TSI/S1 - Reprocessed and Corrected: Sky filter thresholds

DATA REPROCESSED and CORRECTED: 


The data were reprocessed after changing the sky filter thresholds from clear/thin = 50 
and thin/opaque= 70 to 40 and 60, respectively.

The data were archived November 2016. Please retrieve the reprocessed data for use in your 
analysis. 


ORIGINAL DQR CATEGORY: Red( Incorrect)

SGP/TSI/C1 - Reprocess: Corrupt properties file

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.

OLI/M1 - Severe Storm

The site lost power during a severe winter storm.  Operators on site were not able to get 
out and restart the generators to bring things back up until 1/7/2017.  Most of the 
instruments were brought up at this time, but some problems remained until 1/8/2017
