Near real-time atmospheric and oceanic science products of Himawari-8/9 geostationary satellites over the South China Sea

In pursuit of facilitating weather and marine environment monitoring, fortifying maritime security, and supporting ocean navigation, among other objectives, the initial release of near real-time (NRT) atmospheric and oceanic science products has been formulated. These products stem from Japanese Himawari-8/9 (H8/9) geostationary (GEO) satellites positioned over the South China Sea (SCS), with the development grounded in the antecedent FengYun (FY) geostationary satellite algorithm testbed (FYGAT). The satellite products showcase a temporal resolution of 10 minutes and a gridded resolution of 0.05° × 0.05°, spanning from November 3, 2022, to the present. These regional H8/9 GEO satellite science products encapsulate diverse critical data, encompassing cloud mask, fraction, height, phase, optical and microphysical properties, layered precipitable water, sea surface temperature, and more. The dataset is archived in .h5 data formats. The paper regarding this dataset is planned for submission to the journal "Earth System Science Data."
