中国1km分辨率月相对湿度数据集（2007年）

该数据集是中国1km分辨率月相对湿度数据，时间为2007年1—12月。数据基于中国地面824个基准、基本气象台站2007年1—12月本站相对湿度的月值资料，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2007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20071即为2007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 relative humidity data of China at 1 km resolution, spanning January to December 2007. The data is developed based on monthly in-situ relative humidity data from 824 national reference and basic meteorological stations across China for the same period. After strict quality control and screening, spatial interpolation was performed using the 1 km resolution topographic DEM of China as the covariate via the spline method (TPS, Thin Plate Spline) in ANUSPLIN software, generating monthly gridded data at 1 km × 1 km horizontal resolution over China for January to December 2007. For efficient storage, all data are stored as int16 type, with the unit of 1%. Each annual dataset contains 12 data files, which are named by concatenating the year and month. For example, 20071 corresponds to the data of January 2007. The geographic scope 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.
