Available ATBDs

ATBDs are the Algorithm Theoretical Basis Documents.

Here are the ATBDs for candidate GSICS products currently going through the GSICS Procedure for Product Acceptance:

ATBDs for GEO-LEO Inter-Calibration Methods for GEO Imager Infrared Channels

• ATBD for Prototype EUMETSAT Inter-Calibration of SEVIRI-IASI (Currently in Demonstration Mode)
• ATBD for Pre-Operational EUMETSAT Inter-Calibration of SEVIRI-IASI (Candidate for Pre-Operational Mode)
• ATBD for Operational EUMETSAT Inter-Calibration of Meteosat-IASI (Candidate for Operational Mode)

• ATBD for EUMETSAT Demonstration Prime GSICS Corrections for Meteosat-SEVIRI (Candidate for Demonstration Mode)

n.b. The development of experimental wiki-based ATBDs listed below has now been put on hold so as not to delay the submission of products to the GSICS Procedure for Product Acceptance. The current ATBDs are now based on Microsoft Word documents.
