资源简介:
该数据为黄土高原地区逐月降雨量数据,空间分辨率为0.0083333°(1km),时间为1951.1-1960.12。数据格式为netcdf,即.nc格式。该数据集是根据CRU发布的全球0.5°气候数据集以及CNERN发布的中国区高分辨率气候数据集,通过Delta空间降尺度方案在黄土高原地区降尺度生成的。并且,使用黄土高原地区内部及外部113个气象观测点数据进行了验证,验证结果可信。为了便于存储,数据均为int16型存于nc文件中,nc格式数据可用高版本ArcMap(Multidimension Tools)读取生成栅格数据或MATLAB直接读写。该数据集包括1901-1910年逐月降雨数据,一共有120个图层,如果用ArcMap打开,在Dimension选项value处选择所需月份图层。降水单位为0.1mm。如需要提取单点、多点、子区域数据,请联系数据生成者,可提供matlab代码。
This dataset provides monthly precipitation data for the Loess Plateau, with a spatial resolution of 0.0083333° (approximately 1 km), covering the period from January 1951 to December 1960. The data is stored in netCDF format (.nc). This dataset was generated via spatial downscaling over the Loess Plateau using the Delta spatial downscaling method, based on the global 0.5° climate dataset released by CRU and the high-resolution climate dataset for China released by CNERN. It was validated using data from 113 meteorological observation stations within and outside the Loess Plateau, and the validation results confirm its reliability. For efficient storage, the data is saved as int16 type in the .nc files. The netCDF files can be used to generate raster data with recent versions of ArcMap via the Multidimension Tools, or directly read and written using MATLAB. This dataset includes monthly precipitation data from 1901 to 1910, with a total of 120 layers. When opening the dataset with ArcMap, select the target monthly layer via the "value" option in the Dimension tab. The unit of precipitation is 0.1 mm. If you need to extract data for single points, multiple points or sub-regions, please contact the dataset creator, and relevant MATLAB code will be provided.
