Status of Operational AMV Products at EUMETSAT
At EUMETSAT, AMVs are currently derived operationally from the Meteosat geostationary satellites and from the Low Earth Orbit Metop satellites. The current EUMETSAT contribution to the global AMV production covers Meteosat disks at 0 and 41 deg longitudes, the northern and southern high latitude (Poleward 50 deg.) areas with Metop A, Metop B and Metop C single AVHRR wind products, and a global coverage using the Dual AVHRR wind products extracted from the 3 Metop satellites presently placed in Tristar configuration.
In the upcoming years, the transition from current EUMETSAT operational programs Meteosat Second Generation (MSG) and Earth Polar System (EPS) to new generation programs Meteosat Third Generation (MTG) and Earth Polar System Second Generation (EPS-SG) creates some scientific and technical challenges. 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 recent investigation in the extraction of 3D wind profiles from Infrared sounders level 2 products like Metop Infrared Atmospheric Sounding Interferometer (IASI) or the future MTG Infrared Sounder (MTG-IRS) instruments.
This paper will give an overview of the current status of AMV products at EUMETSAT together with information on mid-term perspectives and developments. Emphasis will be given on the expected benefits of the new MTG and EPS-SG instruments capabilities on AMV production.
