【摘要】 以中蒙俄经济走廊的大陆部分为研究区，运用325个气象站点实测数据，结合地形等要素，利用ANUSPLIN气象插值软件对数据进行空间插值，得到中蒙俄经济走廊地区年平均气温1-km栅格数据集(1982–2018)。采用决定系数(R~2)验证插值结果与气象站点数据的相关性，R2均大于0.980。采用平均绝对误差(MAE)和均方根误差(RMSE)作为精度评价指标，MAE和RMSE平均值分别为0.348、0.481℃。数据集包括：(1)研究区边界数据；(2)1982–2018年历年的年平均气温栅格数据。数据集存储为.shp、.tif和.mdd格式，空间分辨率为1km，由159个数据文件组成，数据量为8.65 GB(压缩为2个文件，531 MB)。更多还原

【Abstract】 The spatial-temporal mean temperature dataset in the China–Mongolia–Russia Economic Corridor(1982–2018,1-km/y) was developed based on the data integration of temperature data from 325 meteorological stations in the China–Mongolia–Russia Economic Corridor(CMREC) and on the use of ANUSPLIN meteorological interpolation software.The results show that R~2 was 0.980 and above,where R is the correlation coefficient between meteorological station data and interpolation results.The average mean absolute error(MAE) and root-mean-square error(RMSE) values were 0.348 and 0.481 ℃,respectively.The dataset includes(1) boundary data of the study area and(2) annual-mean-temperature grid data at a 1 km resolution relative to the period 1982–2018.The dataset is archived in.shp,.tif and.mdd data formats and consists of 159 data files with a data size of 8.65 GB(compressed into 2 files of 531 MB).更多还原
