[MSD35-05] Geostationary meteorological satellite of Himawari-10 program and proxy data simulating IR sounder observation
Keywords:Satellite observation, Meteorological satellite, Himawari, Infrared sounder
In Japanese Fiscal Year (FY) 2018, JMA has started considering the Himawari-8/9 follow-on program. The Implementation Plan of the Basic Plan on Space Policy, which is decided/revised by the Strategic Headquarters for National Space Policy, Cabinet Office, Government of Japan, states that “By FY2023 Japan will start manufacturing the Geostationary Meteorological Satellite that will be the successor to Himawari-8 and -9, aiming to put it into operation in around FY2029”. Against this background, JMA completed a contract for Himawari-10 in March 2023 and began related manufacture.
JMA will pursue a seamless geostationary earth orbit satellite system, keeping in mind the CGMS baseline and the WMO Vision for WIGOS in 2040, including in particular the deployment of hyperspectral infrared sounders for the whole geostationary ring. In addition to the visible/infrared imager (Geostationary HiMawari Imager: GHMI), the infrared sounder (Geostationary HiMawari Sounder: GHMS) is planned for Himawari-10 mission to help improve JMA’s services in extreme weather monitoring, nowcasting and numerical weather prediction. In particular, proxy data of GHMS was created to promote utilization and user readiness for the IR sounder, which was contributed by JAMSS, L3Harris and Météo-France. Furthermore, the Space Environmental Suite developed by the Ministry of Internal Affairs and Communications (MIC) and the National Institute of Information and Communications Technology (NICT) will also be mounted on the satellite as hosted payload.
The Himawari series of satellites have been widely used in East Asia and the Western Pacific, representing an indispensable part of this international infrastructure. In this conference, the details of JMA’s program of Himawari-10 with GHMI and GHMS, and proxy data simulating IR sounder for user readiness will be presented.
