摘　　要：气候状况是关系黄河生态保护和高质量发展国家重大战略的重要因素。基于中国地面气候资料日值数据集,选取黄河流域上中游地区及其周边195个气象站点1980-2015年逐月平均气温、最高气温、最低气温、平均相对湿度、平均风速、20-20时降水量、日照时数观测数据,以及运用彭曼法计算得到的潜在蒸散发量,在ANUSPLIN软件平台上,综合考虑地形地貌对气温、风速和湿度空间分异规律的影响,辐射、湿度、风速等因子对潜在蒸散发量的影响,分别构建不同变量的薄盘光滑样条函数,研发了黄河流域上中游地区月度8-km网格气象数据集(1980-2015)。该数据集包括:(1)黄河流域中上游边界数据;(2)1980-2015年逐月平均气温、最高气温、最低气温、平均相对湿度、平均风速、20-20时降水量、日照时数和潜在蒸散发量8 km分辨率月度网格数据。数据集存储为.shp和.img格式,一共包含3,463个文件672 MB(压缩为1个文件,138 MB)。Climate conditions are important factors for the China’s strategy toward the ecological protection and high-quality development of the Yellow River. The monthly/8-km grid meteorological dataset at the middle and upper reaches of the Yellow River basin of China(1980-2015) was developed on the basis of the monthly average temperature, maximum temperature, minimum temperature, average relative humidity, average wind speed, precipitation(accumulated from 20:00 of the previous day to 20:00 of the current day), sunshine hours, and potential evapotranspiration calculated using the Penman-Monteith algorithm at 195 stations surrounding the middle and upper reaches of the Yellow River basin. Using the platform of ANUSPLIN, this study constructed the smooth spline functions of thin plates with different variables by comprehensively considering the influence of topography on the spatial differentiation of air temperature, wind speed, and humidity;and the effects of radiation, humidity, and wind speed on potential evapotranspiration. The dataset includes the following:(1) boundary data of the upper and middle reaches of the Yellow River basin;and(2) monthly/8 km average temperature, maximum temperature, minimum temperature, average relative humidity, average wind speed, precipitation, sunshine hours, and potential evapotranspiration data from 1980 to 2015. The dataset was archived in.shp and.img data formats and consists of 3,463 data files with a size of 672 MB(compressed to a single file with a size of 138 MB).
