Apr 2018: forthcoming data announcement. GERB monthly diurnal cycle products for Obs4MIPS will be released soon. This presentation poster from the European Geosciences Union 2018 meeting describes the product.
Mar 2018: Filled HR products have been used in model comparison, providing insights into the diurnal cycle of Earth outgoing radiation. See ACPD discussion paper, Jan 2018. (doi:10.5194/acp-2017-1144)
Sep 2012: GERB-1 Edition 1 L2 ARG data up to Jul 2012 now available via the NEODC / CEDA web site.
Feb 2011: users of GERB-2 Edition 1 products should apply a post-processing Short Wave calibration update. Users should multiply GERB-2 Edition 1 Short Wave values by 0.976. Further details are available in the 2011 update of the Quality Summary.
The Level 1.5 and Level 2 products are written as HDF5 files. For further information on HDF5 and the Hierarchical Data Format, follow the link to the HDF home page from our Links page.
A number of products with known defects have been excluded from the Edition 1 dataset. See:
Level 2 products
The quality summary documents should be read by all users of Level 2 products.
Latest released dataset documents: 2018 Edition 1 release of Level 2 HR and ARG products.
The RMIB Level 2 products user guide gives details of product format and contents.
Older Level 2 quality documents
The 2011 Level 2 ARG Edition 1 data quality summary is kept here for historical reference.
Level 1.5 products
The Level 1.5 NANRG Edition 1 data quality summary should be read by all users of the Edition 1 Level 1.5 NANRG product.
The GGSPS Products User Guide describes the data format and contents of the Level 1.5 NANRG (Non-Averaged, Non-Rectified, Geolocated) product.
Update, Feb 2011: Users should multiply GERB-2 Edition 1 Short Wave values by 0.976. Further details are available in the updated Quality Summary.
A parameter file description for GERB-2 provides details of calibration tables and access to the versions currently used by the GGSPS.
GERB-2 instrument spectral response
The spectral reponse files available here are the values used in generation of the Edition 1 data set. These are averages over all pixels. The spectral response is used in unfiltering the data during Level 2 processing by RMIB.
A parameter file description for GERB-1 provides details of calibration tables and access to the versions currently used by the GGSPS.
GGSPS processing and products
The GGSPS receives raw GERB data packets and processes the data into science products 24 hours per day, in Near-Real Time (NRT). The MSG satellite transmits GERB data to the MSG ground station at EUMETSAT. From EUMETSAT the GERB packets are transmitted over a network link to the GGSPS. The GGSPS receives a GERB packet every 0.6 seconds, and combines these packets into GERB Level 0 files spanning one instrument scan (in NORMAL mode). These Level 0 files form the input to the GGSPS science processing.
The principal outputs are the Level 1.5 ARG (Averaged, Rectified, Geolocated) radiance product and the L2, 15 minute, products from RMIB (the Royal Meteorological Institute of Belgium). L2 monthly mean fluxes will be generated from the RMIB L2 products. The GGSPS also generates a L1.5 NANRG (Non Averaged, Non Rectified, Geolocated) radiance product (principally for the RMIB).
