Berkeley Earth Combined Land and Ocean Temperature Field, Jan 1850-Nov 2019

These files contain a copy of the Dec 2019 version of the Berkeley Earth Land and Ocean gridded temperature dataset. The files present monthly temperature anomalies across the globe from January 1850 until November 2019. This is created by merging the Berkeley Earth land surface temperature dataset with a reinterpolated version of the HadSST ocean surface dataset. Two versions are available, one that extrapolates land air temperature over sea ice regions, and an alternative construction that extrapolates sea surface temperatures in sea ice regions. The version based on air temperature is recommended for most applications. Gridded NetCDF files are presented on either a 1 degree by 1 degree latitude-longitude grid or a 15984 element equal-area grid. The equal-area grid is used in the construction of the dataset, whereas the 1 degree grid is created at the end of the analysis for convenience. In additional, text files are provided containing global average time series and uncertainties for convenience. A new version of this dataset is created every month.

背景概述

该数据集是伯克利地球组织发布的全球温度异常网格化数据集，覆盖1850年1月至2019年11月的月度数据，通过融合陆地表面温度和海洋表面观测创建。它提供两种网格版本（1度经纬度网格和等面积网格）以及全球平均时间序列，重点用于气候变化和全球变暖研究，并基于开放许可证（CC BY 4.0）每月更新。
