本数据集基于1970—2017年流域内气象站点的实测资料，选取降水、平均温度、和潜在蒸散发三个气象变量，采用泰森多边形的方法，构建了流域面气象数据集。\n
数据集完整覆盖48年时间尺度（1970—2017年），通过采用泰森多边形法计算各气象站观测值的流域面平均值，有效提升了面气象要素估算的可靠性与空间代表性，适用于流域水文气象与径流模拟研究。\n
数据包含汉江流域安康站以上的面降水数据（mm）、平均温度（℃）、和潜在蒸散发（mm）数据。", "ds_source": "

The dataset completely covers the 48-year time scale (1970-2017). By using the Tyson polygon method to calculate the basin average of the observed values at each meteorological station, the reliability and spatial representation of the estimation of regional meteorological elements are effectively improved. It is suitable for basin hydrometeorology and runoff simulation research.\r\n
