中国1km分辨率月平均气压数据集（2003年）

该数据集是中国1km分辨率月平均气压数据，时间为2003年1—12月。数据基于中国地面824个基准、基本气象台站2003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2003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20031即为2003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 mean surface atmospheric pressure data of China at 1 km spatial resolution, covering the period from January to December 2003. The data is derived from monthly station-based mean surface pressure records collected from 824 national reference and basic meteorological stations across China during January to December 2003. After strict quality control and screening, spatial interpolation was conducted using the Thin Plate Spline (TPS) method in ANUSPLIN software, with the 1 km-resolution topographic DEM of China as the covariate, to generate monthly gridded surface data of China with a spatial resolution of 1 km × 1 km for each month from January to December 2003. To facilitate data storage, all data are stored as int16 type, with a unit of 0.1 hPa. Each annual dataset contains 12 data files. The naming convention for the data files follows the format of year + month; for example, "20031" corresponds to the data for January 2003. The geographic coverage of this dataset includes the main land areas of China (including Hong Kong, Macau and Taiwan regions), excluding regions such as the South China Sea islands and reefs.
