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."

为助力气象与海洋环境监测、强化海上安全保障、支撑远洋航行等目标，本数据集已发布首批近实时（NRT）大气与海洋科学产品。该系列产品源自部署于南海（SCS）上空的日本葵花八号/九号（Himawari-8/9, H8/9）对地静止（GEO）卫星，其研发工作依托此前的风云（FY）对地静止卫星算法测试平台（FYGAT）完成。该卫星产品的时间分辨率为10分钟，网格分辨率为0.05°×0.05°，数据覆盖时段为2022年11月3日至今。这批面向区域的H8/9对地静止卫星科学产品涵盖多类核心数据，包括云掩膜、云量、云高、云相态、光学与微物理特性、分层可降水量、海表温度等。本数据集采用.h5格式进行归档存储。有关本数据集的学术论文已计划投稿至《Earth System Science Data》期刊。
