HadEX3：全球极端气候指数(1901-2018)

HadEX3是基于全球地表资料的极端气候数据集，由世界气象组织CCl/CLIVAR/ JCOMM联合协调的气候变化检测和指数专家团（Expert Team on Climate Change Detection and Indices，ETCCDI）研制，包括1901~2018年的29个气温、降水指数，这些指数来自于气象站日观测数据，采用角距离加权法内插到1.25° ×1.875°网格上得到的季节值或年值。
数据集中的NetCDF数据文件采用了1961-90参考期（以便与HadEX、HadEX2和WMO长期气候学评估相匹配），有些指数采用了1981-2010参考期。还有一些数据采用了"climdex" format。

HadEX3 is an extreme climate dataset based on global surface observational data, developed by the Expert Team on Climate Change Detection and Indices (ETCCDI), which is jointly coordinated by the World Meteorological Organization's CCl/CLIVAR/JCOMM. It covers 29 temperature and precipitation indices spanning the period from 1901 to 2018. These indices are derived from daily meteorological station observations, and are interpolated onto a 1.25° × 1.875° grid using the angular distance weighting method to produce seasonal or annual values. The NetCDF data files in this dataset adopt the 1961–1990 reference period (to match the baselines of HadEX, HadEX2 and WMO long-term climatological assessments), while some indices use the 1981–2010 reference period. Additionally, some of the data are stored in the "climdex" format.
