雅鲁藏布江流域水文过程模拟

该数据集为雅鲁藏布江流域水文过程模拟。使用雅鲁藏布江奴下站以上部分站点1970/01/01-2013/12/31的1h尺度的流量模拟数据。以TPMFD数据集中的降水、气温与风速数据驱动VIC模型（网格尺度为0.25°*0.25°，时间尺度为1h）生成网格产流数据，利用退水系数法计算坡面汇流（时间尺度为1h），利用马斯京根法计算河网汇流（时间步长为1h，空间步长为1000m），得到计算流域的1h尺度流量过程，单位为m³/s。流量文件为序列过程，可用文本文件等读取。

This dataset is a hydrological process simulation for the Yarlung Zangbo River Basin. It uses hourly flow simulation data from partial hydrological stations upstream of the Nuxia Hydrological Station on the Yarlung Zangbo River, covering the period from 1970/01/01 to 2013/12/31. Grid-scale runoff generation data was generated by driving the VIC model (with a grid resolution of 0.25° × 0.25° and 1-hour temporal resolution) using precipitation, air temperature, and wind speed data from the TPMFD dataset. Slope flow routing was conducted using the recession coefficient method with a 1-hour temporal resolution, and channel network flow routing was performed using the Muskingum method with a 1-hour time step and 1000 m spatial resolution, yielding hourly flow processes for the studied basin in units of m³/s. The flow files are sequential time series that can be read via text files or other compatible formats.
