RGP : Requirements
RGP : Project Management Plan
01/02/2000 | MSG-RMIB-GE-PL-0001 {{http://gerb.oma.be/icons2/pdficon.gif}} This document gives an overview of the management of the RMIB GERB Processing (RGP) project. This project aims at fullfilling the requirements given in document MSG-RMIB-GE-RS-0001. The documentation related to the project is listed in MSG-RMIB-GE-LS-0001. |

RGP-SP : Spectral Modelling
29/09/1999 | MSG-RMIB-GE-TN-0005 This document describes the spectral modeling module within the SEVIRI Processing (SP) subsystem of the near real time RMIB GERB Processing (RGP) system. This document is currently not available because under revision |
RGP-SP : Scene Identification
29/09/1999 | MSG-RMIB-GE-TN-0007 The purpose of this document is to give a detailed overview of the scene identification process that will run at RMIB on the flow of Meteosat or SEVIRI data. In the RGP, the scene identification is needed mainly to select adequate angular dependency model for the radiances to fluxes conversions. This document is currently not available because under revision |
RGP-SP : Angular Modelling
01/02/2006 | MSG-RMIB-GE-TN-0008 The purpose of this document is to give a detailed overview of the angular dependency models that are used in the RGP. It explains how the unfiltered broadband radiances measured in the direction of the MSG satellite are converted into TOA fluxes. This document is currently not available because under revision |

ROLSS ICD
02/09/2001 | MSG-RMIB-GE-IF-0001 (MS-word) The purpose of this document is to specify all aspects of the interface between the RMIB On Line Short term Services (ROLSS) and GERB L2 users, with respect to data products that will be provided in a timely fashion during the operational lifetime of the GERB 1 instrument. This ICD is one of the two which define the interfaces of the RMIB GERB Ground Segment Processing System. |
RGP : Data Products Description
11/02/2000 | MSG-RMIB-GE-IF-0002 {{http://gerb.oma.be/icons2/pdficon.gif}} The purpose of this document is to give a description of the data products that will be provided bt the RMIB to external users. External users include the RAL based GGSPS for the level 2 non real time flux product and real time users for real time flux products. |

Technical Notes
Generation of a Data Base of TOA Spectral Radiance Fields
09/07/2004 | MSG-RMIB-GE-TN-0030 This technical note describes the generation, using the SBDART radiative transfer model, of a large data base of spectral radiance fields at the top of the atmosphere. This data base is of great importance to parameterize some subsystems within the GERB processing at RMIB, for instance the spectral modeling. In particulate, the document present the generation of physically realistic Earth and atmosphere conditions. This document is currently not available because under revision |
Correction of the dispersion in the GERB's detector spectral response curves
12/07/2007 | MSG-RMIB-GE-TN-0031 {{http://gerb.oma.be/icons2/pdficon.gif}} This technical note quantifies the errors introduced in the GERB final products due to the dispersion of spectral response (SR) curves between the different GERB detectors. This dispersion is the cause of a dispersion of the detector's filtered radiances for a given observed scene. This document proposes a practical way to reduce the problem introduced by this dispersion for the RMIB GERB processing by a preliminary correction of the detector's radiances before the unfiltering process. |
Direct Unfiltering of GERB Data
21/01/2003 | MSG-RMIB-GE-TN-0035 {{http://gerb.oma.be/icons2/pdficon.gif}} This technical note describes the transformation of the GERB SW and LW filtered measurements into unfiltered solar and thermal radiances. The method is called “direct unfiltering” as none spectral information from SEVIRI is needed, in contrario with the operational GERB unfiltering which uses some spectral information from the SEVIRI imager. This technical note provides the laws and parameters for the direct unfiltering of the GERB-2 and GERB-1 with the more recent version of the spectral response curves. |
Meteosat Count versus CERES-TRMM Unfiltered Radiance
10/09/2003 | MSG-RMIB-GE-TN-0036 {{http://gerb.oma.be/icons2/pdficon.gif}} A database of colocated and coangular pairs of Meteosat-[5,7] and CERES-TRMM shortwave radiances has been built. From this data base, it is possible to derive simple parameterizations to estimate the broadband unfiltered shortwave radiance at TOA directly from the Meteosat count images. This technical note describes the data base and shows the scatter plots of the pairs Meteosat/CERES data. |

GERB-2 V998 (Ed.1) ARG Radiances and Fluxes Intercomparison with CERES SSF Data
GERB-2 Ed.1 ARG Radiances and Fluxes Intercomparison with CERES SSF Data
17-07-2007 | MSG-RMIB-GE-TN-0043 {{http://gerb.oma.be/icons2/pdficon.gif}} This technical note shows that the radiances and fluxes provided in the 3 main GERB level 2 formats (i.e. the ARG, BARG and HR formats) are consistent one to the others. That means that equivalent values are obtained when the GERB products are averaged over sufficiently large areas and time interval. |
