中国1km分辨率月平均气温数据集（1997年）

该数据集是中国1km分辨率月平均气温数据，时间为1997年1—12月。数据基于中国地面824个基准、基本气象台站1997年1—12月本站平均气温的月值资料，数据经过严格的质量控制和筛选后，采用全国1km分辨率的地形图DEM为协变量，利用ANUSPLIN软件的样条法 （TPS，Thin Plate Spline）进行空间插值，生成1997年1—12月的中国地面水平分辨率1km×1km的月格点数据，为便于存储数据均为int16型，数据单位为0.1℃。每年数据集包含12个数据体，数据体命名采用年份+月份，如19971即为1997年1月数据。本数据集包含的地理空间范围是全国主要陆地（包含港澳台地区），不含南海岛礁等区域。This dataset provides monthly average air temperature data at 1 km resolution for China, covering the period from January to December 1997. It is developed based on monthly average air temperature records from 824 national standard and basic meteorological stations across China for the same period. After strict quality control and screening, spatial interpolation was performed using the Thin Plate Spline (TPS) method in ANUSPLIN software, with the national 1 km resolution topographic DEM as the covariate. As a result, monthly grid point data of China's land surface with a horizontal resolution of 1 km × 1 km for January to December 1997 were generated. All data are stored as int16 type for convenient storage, with the unit of 0.1℃. Each annual dataset includes 12 data files, which follow a naming convention of year plus month; for example, 19971 corresponds to the data for January 1997. The geographic coverage of this dataset includes the main land areas of China (covering Hong Kong, Macao and Taiwan regions), excluding regions such as the South China Sea reefs and other outlying islands.
