Status of AMVs from Fengyun Satellites
This paper briefly introduces status of operational AMVs at NSMC/CMA. Recent improvements, new additions, processing changes and monitors, future plans of the Atmospheric Motion Vector (AMV) product suite will be discussed. The current satellite constellation for operational AMVs processing includes FY-2G (99.5oE), FY-2H (79oE) and FY-4A(104.7oE). FY-2H, the 8th (last) unit of the FY-2 series satellites, was operational in October 2018 and FY-4A, the first unit of FY-4 series (CMA new-generation geostationary meteorological satellite series), was placed into operation in May 2018. Several new enhancements in the NSMC/CMA AMVs operational processing are implemented and being implemented. These main enhancements include replacement of 6-hour FY-2H AMV to 30-minute in northern hemisphere, and of FY-4A 6-hour FY-2H AMV to 3-hour in full disk. Updates on the status of these enhancements and other plans will be presented. Meanwhile, polar wind products from FY-3D satellite are being developed and will be operational in 2020.
