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 ; |

Subject: | 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. |
