Abstract

Japan Meteorological Agency's Himawari-8 and -9 geostationary meteorological satellites are scheduled to continue operation until around 2029. As the Himawari series cover a wide variety of uninterrupted domestic and international observations, Japan Meteorological Agency (JMA) began the building of the new Himawari-10 satellite in March 2023 toward launch in Japan Fiscal Year (JFY) 2028 and operation in JFY2029, in accordance with the Basic Plan on Space Policy approved by the Cabinet of Japan on 13 June, 2023. The Himawari-10 initiative remains dedicated to ongoing development of weather observation and forecasting capability with new hyperspectral infrared sounder data to support issues such as disaster risk reduction in East Asia and the Western Pacific. This paper overviews the Himawari-10 project and onboard observation equipment.
