- Since 2004, top-of-atmosphere (TOA) broadband reflected solar and emitted thermal radiances and fluxes are provided by the Geostationary Earth Radiation Budget (GERB) instruments (Harries et al., 2005) on board of the Meteosat Second Generation (MSG) satellites.
- The repeat cycle of GERB of 15 minutes allows to resolve the diurnal cycle of the shortwave (SW) and longwave (LW) radiation fluxes at the TOA.
- Location of the operational GERB instrument: Longitude 0° (2004-now) and an additional GERB instrument at longitude 41.5° (2016-now).
- GERB products: NANRG (Nonaveraged, nonrectified, geolocated), ARG (Averaged, rectified, geolocated), BARG (Binned, averaged, rectified, geolocated), HR (High-resolution) in different levels (L1.5, L2, L3), with different spatial (44 km and 9 km) and temporal resolutions (e.g. instantaneous, 15 min bins, monthly mean). All data products are also available in near real-time (NRT).
- Shown are on one hand an overview about the GERB data sets, and on he other hand some preliminary results of a comprehensive analysis and validation of the (so far) 17 years of GERB data. The results of the validation will thereafter be used to better understand and improve the GERB data set itself before releasing a new edition.
