资源简介:
该数据为黄土高原地区逐月最高温度数据,空间分辨率为0.0083333°(约1km),时间为1971.1-1980.12。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,最高温单位为 0.1℃。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1971-1980年逐月最低气温数据,一共有120个图层,如果用ArcMap打开,在Dimension选项value处选择所需月份打开。 如需要提取单点、多点、子区域数据,请联系数据生成者彭守璋,可提供matlab代码。Email:szp@nwafu.edu.cn

This dataset contains monthly maximum temperature data for the Loess Plateau, with a spatial resolution of 0.0083333° (approximately 1 km), covering the period from January 1971 to December 1980. The data is stored in NetCDF format, i.e., .nc files. It was downscaled to the Loess Plateau using the Delta spatial downscaling method, based on the global 0.5° climate dataset released by the Climatic Research Unit (CRU) and the high-resolution climate dataset for China released by the China Ecosystem Research Network (CNERN). Moreover, it was validated using data from 113 meteorological observation stations both within and outside the Loess Plateau, and the validation results are reliable. To facilitate storage, the data is stored as int16 type in the .nc files, with the unit of maximum temperature being 0.1℃. NetCDF format data can be read to generate raster data using high-version ArcMap (via the Multidimension Tools), or directly read and written via MATLAB. This dataset includes a total of 120 layers corresponding to monthly maximum temperature data from 1971 to 1980. When opening it with ArcMap, select the desired month in the "value" option of the Dimension tab to load the corresponding data. If you need to extract data for single points, multiple points or sub-regions, please contact the dataset creator Peng Shouzhang, and MATLAB code will be provided. Email: szp@nwafu.edu.cn
