Status of Operational and Future Atmospheric Wind Products at EUMETSAT
The current EUMETSAT contribution to the global AMV production covers Meteosat disks at 0 and 45.5 deg longitude, the northern and southern high latitude (poleward of 50 deg) areas with Metop-B and Metop-C single AVHRR wind products, and global coverage using the Dual AVHRR wind products extracted from the two Metop satellites.
With the launch of MTG-FCI mid-december 2022 EUMETSAT is starting the transition from its current operational programmes, Meteosat Second Generation (MSG) and EUMETSAT Polar System (EPS), to new generation programmes, Meteosat Third Generation (MTG) and EUMETSAT Polar System Second Generation (EPS-SG). The strategy adopted for AMV development considers several critical aspects such as the continuity of current operation capabilities, and the development of new capabilities to fulfil increasing user needs. These last ones mainly concern algorithms under development for EPS-SG/METImage and Sentinel-3 Sea and Land Surface Temperature Radiometer (SLSTR) instruments, but also the extraction of 3D wind profiles from infrared sounder level 2 products like the Metop Infrared Atmospheric Sounding Interferometer (IASI) or the future MTG Infrared Sounder (MTG-IRS) instruments. Finally, following the great success of the ESA Aeolus mission, EUMETSAT is now working with ESA on the preparation of a potential follow-on operational mission, named EPS-Aeolus, to further fulfil the need for such observations.
This paper will summarise the current operational status, upcoming changes and future developments of all these atmospheric wind products at EUMETSAT.
