延河流域25m分辨率年平均气温数据集（2010-2021年）

数据集为延河流域年平均气温数据集，时间为2010-2021年，空间分辨率25m，基于专业气象插值软件ANUSPLIN 以延河流域及周边2010-2021年105 个气象站点逐日平均温度资料为基础，引入25 m数字高程模型作为协变量进行插值，从而获得延河流域年平均温度栅格数据，选取数据的 15%作为验证集，选取过程采用随机抽样，将随机站点数据与插值结果进行比较，实测值与预测值进行相关性分析，该结果与观测结果拟合较好，说明了结果的可靠性。This dataset is the annual average air temperature dataset for the Yanhe River Basin, spanning the period from 2010 to 2021 with a spatial resolution of 25 meters. Based on the daily average temperature data collected from 105 meteorological stations within and around the Yanhe River Basin during 2010–2021, the professional meteorological interpolation software ANUSPLIN was utilized, with the 25 m digital elevation model (DEM) introduced as a covariate to perform interpolation, thereby generating the gridded annual average air temperature data for the Yanhe River Basin. Subsequently, 15% of the dataset was randomly selected as the validation set. Randomly sampled in-situ station data were compared with the interpolation results, and correlation analysis was conducted between the measured and predicted values. The good agreement between the modeled outputs and observational data verifies the reliability of this dataset.
