黑河上游河川径流量、蒸散发和降水量数据集（1992-2015）

本数据为黑河上游1992-2015年生长季降水产生的径流、蒸散发，数据内容包括：降水（mm）、蒸散发（mm）、径流（mm）、土壤含水量（m3/m3）。时间分辨率：年（生长季），空间分辨率：0.00833°。数据是基于Eagleson生态水文模型使用气象、土壤、植被参数模拟获得的，模拟的降雨径流使用黑河上游6个子流域（黑河干流、八宝河、野牛沟、梨园河、瓦房城、洪水河）的生长季观测径流数据进行了验证，相关系数（R）的变化范围为0.53-0.74，RMSE在32.46-233.18 mm之间，相对误差范围为-0.66--0.0005；模拟蒸散发与GLEAM ET之差在−115.36 mm 到 44.1 mm之间。模拟结果可以为黑河上游水文模拟提供一定参考。

This dataset contains runoff and evapotranspiration driven by precipitation during the growing seasons from 1992 to 2015 in the upper Heihe River Basin. The specific variables included are: precipitation (mm), evapotranspiration (mm), runoff (mm), and soil moisture content (m³/m³). Temporal resolution is annual (growing season), with a spatial resolution of 0.00833°. This dataset was generated via simulations using the Eagleson ecohydrological model, with inputs of meteorological, soil and vegetation parameters. The simulated runoff was validated against in-situ observed runoff data collected during the growing seasons from six sub-basins in the upper Heihe River Basin, including the main stem of the Heihe River, Babao River, Yeniugou, Liyuan River, Wafangcheng and Hongshui River. The correlation coefficient (R) ranges from 0.53 to 0.74, the root mean square error (RMSE) falls between 32.46 and 233.18 mm, and the relative error ranges from -0.66 to -0.0005. The discrepancy between the simulated evapotranspiration and GLEAM ET products ranges from -115.36 mm to 44.1 mm. These simulation results can provide valuable references for hydrological simulation studies in the upper Heihe River Basin.
