NOAA Global Surface Temperature Dataset, Version 4.0

The NOAA Global Surface Temperature Dataset (NOAAGlobalTemp) is derived from two independent analyses: the Extended Reconstructed Sea Surface Temperature (ERSST) analysis and the land surface temperature (LST) analysis using the Global Historical Climatology Network (GHCN) temperature database. The data is merged into a monthly global surface temperature dataset dating back from 1880 to the present, updated monthly, in gridded (5 degree x 5 degree) and time series formats. This data set is used in climate monitoring assessments of near-surface temperatures on a global scale. The changes from version 3.5.4 to version 4.0.0 include an update to the primary input dataset (ERSST) now at version 4.0.0 and GHCN-Monthly now at version 3.3.0. This dataset is formerly known as Merged Land-Ocean Surface Temperature (MLOST).

美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）全球地表温度数据集（NOAAGlobalTemp）源自两项独立分析：扩展重建海表温度（Extended Reconstructed Sea Surface Temperature，ERSST）分析，以及依托全球历史气候学网络（Global Historical Climatology Network，GHCN）温度数据库开展的陆表温度（Land Surface Temperature，LST）分析。该数据集被整合为一套可追溯至1880年至今的月度全球地表温度数据集，每月更新一次，提供5°×5°网格化与时序两种数据格式。本数据集用于全球尺度近地表温度的气候监测评估工作。从3.5.4版本升级至4.0.0版本的更新内容包括：将核心输入数据集ERSST升级至4.0.0版本，同时将GHCN月值数据集升级至3.3.0版本。该数据集曾用名为合并陆海地表温度数据集（Merged Land-Ocean Surface Temperature，MLOST）。
