Data Stewardship Maturity Report for GHRSST Level 4 RAMSSA Australian Regional Foundation Sea Surface Temperature Analysis (GDS version 1)

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis, produced daily on an operational basis at the Australian Bureau of Meteorology (BoM) using optimal interpolation (OI) on a regional 1/12 degree grid over the Australian region (20N - 70S, 60E - 170W). This Regional Australian Multi-Sensor SST Analysis (RAMSSA) v1.0 system blends satellite SST observations from passive infrared and passive microwave radiometers, with in situ data from ships, Argo floats, XBTs, CTDs, drifting buoys and moorings from the Global Telecommunications System (GTS).

高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature, GHRSST）四级海表温度分析产品，由澳大利亚气象局（Australian Bureau of Meteorology, BoM）以业务化运行模式每日生成。该产品基于澳大利亚区域（20°N - 70°S，60°E - 170°W）的1/12度区域网格，采用最优插值（optimal interpolation, OI）方法计算生成。此澳大利亚区域多传感器海表温度分析（Regional Australian Multi-Sensor SST Analysis, RAMSSA）v1.0系统，融合了被动红外与被动微波辐射计获取的卫星海表温度观测数据，以及来自全球电信系统（Global Telecommunications System, GTS）的船舶、Argo浮标、投弃式温深计（XBT）、温盐深仪（CTD）、漂流浮标与锚系观测站的原位观测数据。
