The Geostationary Earth Radiation Budget (GERB) Project project is carried out in the Remote Sensing from Space group at RMIB that is also active in the Climate Monitoring SAF (CM SAF), the EarthCARE Earth Explorer, and the Copernicus Climate Change Service (C3S).

The “Earth Radiation Budget Workshop” is on-going, in Hamburg, Germany. The GERB team is presenting its latest achievements.

The “Quartz Filter Anomaly” affecting the GERB4 data has been fixed and the GERB4 record (Jan 2018 onward) is under reprocessing. The data is expected to be available in time for presentation at the EUMETSAT 2022 conference in Brussels.

The next “Earth Radiation Budget Workshop” will be held on October 12-14, 2022, in Hamburg, Germany. This workshop is the join meeting of the CERES, ScaRaB, GERB, and Libera science teams.

As part of the MSG2 payload, the GERB1 instrument is now operational over the Western part of the Indian Ocean (subsatellite longitude of 45.5° East). The GERB1 Indian Ocean record starts on 9th May 2022 and is processed in near real time with the version tag V007.

Data available for evaluation via the ROLSS: https://gerb.oma.be/doku.php?id=data_access

Publication of 2 papers in “Remote Sensing” describing the TOA radiation products from AVHRR, one for the shortwave, one for the longwave. These works will be basis to future release of TOA radiation products in the Climate Monitoring SAF CLARA-A3 Climate Data Record.
