GOES-16 (GOES-East) Geostationary Lightning Mapper (GLM) Testing

Beginning on Tuesday, March 16th 2021 at 1630Z, NESDIS will perform testing on the GOES-16 (GOES-East) Geostationary Lightning Mapper (GLM) to improve data products derived from it. This will be the first of multiple 1 hour outages, and one 24-hour degraded product period which are planned from March 16th through March 23rd. The availability or quality of GLM data (e.g., in AWIPS) will be affected during this testing. The outages and degradation period are:
March 16, 1630-1730 UTC: 60 min GLM outage
March 17, 0436-0536 UTC: 60 min GLM outage
March 17, 1630-1730 UTC: 60 min GLM outage
March 18, 0436-0536 UTC: 60 min GLM outage
March 18, 1630-1730 UTC: 60 min GLM outage
March 19, 0436-0536 UTC: 60 min GLM outage
March 22, 1500 UTC to March 23, 1500 UTC: 24 hour GLM degraded radiometric data
The testing does not affect GOES-16 ABI imagery or ABI Level-2/derived products. This testing will be postponed in the event of a critical weather day. Events will slip one business day, remaining at the same time of day, until they do not conflict with critical weather day.
The TOWR-S team will post updates in the “towr-s” room on NWSChat regarding this planned GOES-16 GLM testing. Updates will also be posted on the TOWR-S homepage in the NWS VLab. If you encounter any issues following this instrument testing, please contact Lee Byerle (lee.byerle@noaa.gov) on the TOWR-S team, or direct any questions to the team in the “towr-s” room on NWSChat.
