Global daily 2-m air temperture from ECMWF ERA-Interim Reanalysis

This dataset includes the global daily mean 2-m air temperature data from the European Centre for Medium-Range Weather Forecasts Interim Re-Analysis (ECMWF ERA-Interim). The nodes are selected with a bin width of 2.5 degree for both the latitude and the longitude. Therefore, there are 73 latitude values (from 90 degree north to 90 degree south) and 144 longitude values (from 0 degree east to 360 degree east) in total, as written in each file's name. The length of each record is 35 years (12775 days). The unit of the time series is Kelvin.本数据集涵盖源自欧洲中期天气预报中心临时再分析（ECMWF ERA-Interim）的全球逐日2米高度平均气温数据。该数据集的格点经向与纬向均采用2.5度的格距进行选取，因此总包含73个纬度值（范围为北纬90度至南纬90度）与144个经度值（范围为东经0度至东经360度），该信息已标注于每个文件的文件名中。每条记录的时长为35年，共计12775天，其时间序列的单位为开尔文（Kelvin）。
