Short abstract JAXA operationally produces and distributes various satellite-based SST datasets by using passive microwave, polar-orbital InfraRed and geostationary InfraRed imagers in GDS2.0 format from the JAXA GHRSST server (https://suzaku.eorc.jaxa.jp/GHRSST/) and Himawari Monitor (https://www.eorc.jaxa.jp/ptree/) in near-real-time basis and archives past period data since June 2002. We have updated SGLI SST Ver.3 to improve cloud masks in November 2021 and plan to update AMSR2 SST Ver.4.1 soon. Due to the improved cloud masking, SGLI SST V3.0 in the daytime are retrieved from the SGLI measurements only with pre-calculated RTM-based coefficients and Baysian-based PDFs and are 100% independent from any other in-situ and analysed data. AMSR2 SST Ver.4.1 will correct underestimation trends versus in-situ observations over Northern low- and mid-latitudes since 2019 and provide SST retrievals under high-wind and weak precipitation conditions, which are set to missing in previous versions. We also prepare tuning of Himawari SST algorithm corresponding to planning change-over of the Japanese geostationary satellite from Himawari-8 to -9 scheduled in late 2022. Overlap operations of Himawari-8 and -9 are planned by Japan Meteorological Agency (JMA) for a couple of months to inter-calibrate two SST products. We are also preparing multiple SST products for the AMSR3 onboard the GOSAT-GW satellite to be launched in JFY2023. Those products will succeed SST datasets of AMSR-E and AMSR2 and improve robustness of SST retrievals and spatial resolution by adding new channels in 10-GHz. We will introduce the latest status of SST datasets and future plans for AMSR3.

宇宙航空研究開発機構（JAXA）が所有する膨大な地球観測データを，異なる分野のユーザであっても簡単に利用できる仕組みを提供し，データの利用用途を広げることを目的として，地球観測データのWEB API（JAXA OPEN API）を整備した．また，そのAPI を利用したアプリケーションの開発コンテスト（JAXA OPEN API COMPETITION）を開催し，地球観測データを利用した多くのアプリケーションが創造されることを実証した．本稿では，これらの一連の活動と本活動がもたらす成果について述べる．, JAXA OPEN API is a Web API (Application Programming Interface) designed to provide simple and efficient access to people beyond the public sector, including scientific and educational fields, with a view to promoting the broader sharing of Earth science data. In order to demonstrate the efficacy and usability of the API, Japan Aerospace Exploration Agency (JAXA) held a competition to develop innovative applications by taking advantage of the global Earth science data. This paper describes the activity and results for expanding the use of Earth science data using the JAXA OPEN API., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1630012013, レポート番号: JAXA-RR-15-006
