Subject: | SGP/TSI/C1 - Water on lens |
DataStreams: | sgptsiskycoverC1.b1 |
Description: | After a rain episode, drops of water collected on the lens window causing the cloud fraction values to be suspect. To prevent this, a drip edge was formed around the bottom of the enclosure with thick electrical or splicing tape. |

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. |
