EUMETSAT and NOAA GSICS GEO-LEO IR Correction Products in Pre-Op Phase

Dear Tim:

On behalf of the GSICS Coordination Center (GCC) and GSICS Product Acceptance Team (GPAT), I am pleased to announce that the EUMETSAT GSICS GEO-LEO IR inter-calibration correction product for Meteosat/SEVIRI and the NOAA GSICS GEO-LEO IR inter-calibration correction product for GOES Imager are now in pre-operational phase. These two products have completed the required documentation including the Algorithm Theoretical Basis Document (ATBD), uncertainty analysis and other ancillary reports. The software for these two products is running stably and reproducibly with minimal code changes expected. The software for the NOAA product has been maintained with the subversion control package. The product data availability and metadata have also been running reliably and stably at the GSICS data servers over the past years. We have received some positive feedback from product users and continue to encourage user comments. Per the GSICS Procedure for Product Acceptance (GPPA) and the SCOPE-CM maturity model, these two products are now in pre-operational phase, on the way to operations.

Users can access to the products and the associated documents freely at the GSICS product catalog, which is also linked to the WMO GSICS portal website. The corresponding products in demo version will be no longer available at the GSICS server.

Best Regards,
Fangfang Yu
Deputy Director of GCC
