中国1km分辨率月平均气压数据集(2000年)
收藏资源简介:
该数据集是中国1km分辨率月平均气压数据,时间为2000年1—12月。数据基于中国地面824个基准、基本气象台站2000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2000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20001即为2000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 mean air pressure data for China at a 1 km spatial resolution, covering January to December 2000. The data is based on monthly mean station air pressure records from 824 national reference and basic meteorological stations across China during January–December 2000. After strict quality control and screening, the national 1 km resolution topographic DEM was used as a covariate, and spatial interpolation was conducted using the Thin Plate Spline (TPS) method in the ANUSPLIN software, generating monthly 1 km×1 km grid data of China's land surface for the target period. All data are stored as int16 type for convenient storage, with a unit of 0.1 hPa. Each annual dataset includes 12 data files, named using the format of year + month; for example, 20001 corresponds to the data for January 2000. The spatial scope of this dataset covers the main terrestrial areas of China (including Hong Kong, Macao and Taiwan regions), excluding regions such as the South China Sea islands and reefs.
