中国1km分辨率月日照时数数据集(1993年)
收藏资源简介:
该数据集是中国1km分辨率月日照时数数据,时间为1993年1—12月。数据基于中国地面824个基准、基本气象台站1993年1—12月本站日照时数的月值资料,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1993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 h。每年数据集包含12个数据体,数据体命名采用年份+月份,如19931即为1993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 sunshine duration data at 1km resolution for China, covering January to December 1993. The data is derived from monthly in-situ sunshine duration data collected from 824 national reference and basic meteorological stations across China during January to December 1993. After strict quality control and screening, spatial interpolation was conducted using the Thin Plate Spline (TPS) method in ANUSPLIN software, with the national 1km-resolution topographic DEM as the covariate, to generate monthly gridded data at 1km×1km horizontal resolution over China for the same period. For convenient storage, all data are stored as int16 type, with the unit of 0.1 h. Each annual dataset contains 12 data files, which are named by combining the year and month; for example, 19931 corresponds to the data for January 1993. The geographical 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.
