Sep 2012: GERB-1 Edition 1 L2 ARG data up to Jul 2012 now available via the BADC.
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 updated 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 Level 2 ARG Edition 1 data quality summary should be read by all users of Edition 1 Level 2 products.
The RMIB Level 2 products user guide gives details of product format and contents.
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.

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).
