SGP/TSI/C1 - Icing event
DataStreams:sgptsiskyimageC1.a1, sgptsiskycoverC1.b1, sgptsicldmaskC1.a1
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.

ENA/C1 - Reprocess: Slightly incorrect location fields
DataStreams:enaceilC1.b1, enatsiskycoverC1.b1, enaceilpblhtC1.a0
Description:
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 ;
Measurements:enaceilpblhtC1.a0:
  • North latitude(lat)
  • East longitude(lon)
  • Altitude above mean sea level(alt)
enaceilC1.b1:
  • North latitude(lat)

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.
Measurements:sgptsiskycoverC1.b1:
  • base_time
