中国1km分辨率月平均气压数据集（2011年）

该数据集是中国1km分辨率月平均气压数据，时间为2011年1—12月。数据基于中国地面824个基准、基本气象台站2011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2011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20111即为2011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 pressure data of China at a 1 km spatial resolution, spanning the period from January to December 2011. The data is sourced from monthly mean station-level air pressure records collected from 824 national reference and basic meteorological stations across China during January to December 2011. Following strict quality control and data screening, the thin plate spline (TPS) method within the ANUSPLIN software was applied for spatial interpolation, using the national 1 km resolution topographic DEM as the covariate, to produce monthly 1 km×1 km grid data of China's land surface for each month between January and December 2011. For efficient data storage, all datasets are stored in int16 format, with a unit of 0.1 hPa. Each annual dataset contains 12 data files, which are named by combining the year and month. For example, the file named 20111 corresponds to the air pressure data for January 2011. The geographic coverage of this dataset includes the main land areas of China (encompassing Hong Kong, Macao and Taiwan regions), excluding regions such as the South China Sea islands and reefs.
