摘要
相对湿度与大气污染物的扩散、迁移和转化密切相关,是区域生态环境质量评估的重要指标。基于黄河流域所在的九省区及周边940个气象站点2000-2015年逐月相对湿度观测数据,在ANUSPLIN软件平台上以高程作为独立协变量,采用三次样条函数进行插值,生成黄河流域九省区相对湿度时空分布数据集(2000-2015)。数据时间分辨率为月,空间分辨率为1 km,投影方式为阿尔伯斯等面积投影,坐标系为WGS-84。数据集存储为.tif格式。
Relative humidity is closely related to the diffusion,migration,and transformation of air pollutants and is an important index for regional environmental quality assessment.Based on the observation data from 940 meteorological stations in nine provinces and their surrounding areas in the Yellow River Basin,we generated the relative humidity dataset with 1-km resolution for nine provinces in the Yellow River Basin(2000-2015),using the ANUSPLIN software platform.The cubic spline function was applied for interpolation,with elevation as an independent covariate.The temporal resolution of the data was month,the spatial resolution was 1 km,and the projection was based on Albers Conical Equal Area with the coordinate system of WGS-84.The data are provided in the.tif format.
