GHRSST Level 4 OSPO Global Nighttime Foundation Sea Surface Temperature Analysis (GDS version 2)

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis produced daily on an operational basis at the Office of Satellite and Product Operations (OSPO) using optimal interpolation (OI) on a global 0.054 degree grid. The Geo-Polar Blended Sea Surface Temperature (SST) Analysis combines multi-satellite retrievals of sea surface temperature into a single analysis of SST. This analysis includes only nighttime data from sensors that include the Advanced Very High Resolution Radiometer (AVHRR), the Visible Infrared Imager Radiometer Suite (VIIRS), the Geostationary Operational Environmental Satellite (GOES) imager, the Japanese Advanced Meteorological Imager (JAMI) and in situ data from ships, drifting and moored buoys. This analysis was specifically produced to be used as a lower boundary condition in Numerical Weather Prediction (NWP) models. This dataset adheres to the GHRSST Data Processing Specification (GDS) version 2 format specifications.

本数据集为高分辨率海表温度（GHRSST）第4级海表温度分析，由卫星与产品运行办公室（OSPO）在运行基础上，每日采用最优插值法（OI）在全球0.054度网格上进行生成。地理极地混合海表温度（SST）分析将多卫星获取的海表温度数据综合为单一的海表温度分析。该分析仅包括夜间数据，数据来源于搭载高级甚高分辨率辐射计（AVHRR）、可见光红外成像仪辐射计套装（VIIRS）、地球同步轨道运行环境卫星（GOES）成像仪、日本高级气象成像仪（JAMI）的传感器，以及来自船舶、漂流和系留浮标的现场数据。此分析特别编制，旨在作为数值天气预报（NWP）模型的底部边界条件。本数据集遵循GHRSST数据处理规范（GDS）第2版格式规范。
