摘要
为研究不同降水产品在中国西南地区流量模拟中的适用性，对比了5种卫星降水产品(CHIRPS、CMORPH、TRMM、PERSIANN、IMERG)和1种再分析降雨数据(ERA5)在大湟江流域的精度及其用于流域流量模拟的可行性，并调查了模型校正对降雨误差的弥补效应。结果表明，ERA5日降雨量与雨量站点实测数据(参考降雨)最接近，但严重高估了年降雨量，CHIRPS、TRMM和PERSIANN日降雨量与参考降雨的相似度最低，IMERG、TRMM和PERSIANN的年降雨量最接近参考降雨。整个模拟期内，参考降雨的流量模拟结果最佳，CHIRPS和PERSIANN的结果最差，CMORPH、TRMM和IMERG的结果略差于参考降雨。模型校正能有效弥补ERA5的降雨误差，显著改善其模拟结果，模型校正对其他降雨数据模拟结果的影响有限。
