中国1km分辨率月平均气温数据集（2005年）

该数据集是中国1km分辨率月平均气温数据，时间为2005年1—12月。数据基于中国地面824个基准、基本气象台站2005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2005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20051即为2005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 is monthly average air temperature data of China at 1km spatial resolution, covering the period from January to December 2005. It is developed based on monthly average air temperature records from 824 national reference and basic meteorological stations across China during January to December 2005. After strict quality control and screening, the thin plate spline method (TPS, Thin Plate Spline) integrated in ANUSPLIN software was used for spatial interpolation, taking the 1km-resolution topographic DEM of China as the covariate, to produce monthly gridded data of China's land surface at 1km×1km resolution for each month from January to December 2005. For convenient data storage, all data values are stored as int16 type, with the unit of 0.1℃. Each annual dataset includes 12 data files, which are named by concatenating the year and month. For example, the file named 20051 corresponds to the data of January 2005. The spatial coverage of this dataset covers the main land areas of China (including Hong Kong, Macao and Taiwan regions), excluding areas such as the South China Sea islands and reefs.
