中国1km分辨率月平均气压数据集（2010年）

该数据集是中国1km分辨率月平均气压数据，时间为2010年1—12月。数据基于中国地面824个基准、基本气象台站2010年1—12月本站平均气压的月值资料，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2010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 hPa。每年数据集包含12个数据体，数据体命名采用年份+月份，如20101即为2010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 pressure data of China at 1 km resolution, covering January to December 2010. The data is derived from monthly mean station air pressure records from 824 national standard and basic meteorological stations across China for the same period. After strict quality control and screening, spatial interpolation was conducted 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 at 1 km × 1 km horizontal resolution for January to December 2010 were generated. For efficient storage, all data are stored in int16 format, with a unit of 0.1 hPa. Each annual dataset includes 12 data files, which are named by concatenating the year and month. For example, 20101 corresponds to the data of January 2010. The geographical coverage of this dataset includes the main land areas of China (including Hong Kong, Macao and Taiwan regions), excluding areas such as the South China Sea islands and reefs.
