Abstract

There are uncertainties in the hydrological application of precipitation data products in different climate zones. In this study, the precipitation data of NOAA-CPC-US is used as a reference to evaluate the accuracy of satellite precipitation data products, such as PERSIANN, GPM-IMERG, radar StageIV, and climate model ERA5, in different climate zones in the USA. The results show that StageIV has the best estimation accuracy in different climatic zones, followed by GPM-IMERG, PERSIANN, and ERA5 numerical model. The data products were used to drive the CREST distributed hydrological model to evaluate their runoff simulation effectiveness. StageIV and NOAA-CPC-US have a better effect in runoff simulation of different climate zones to meet runoff simulation. The GPM-IMERG and PERSIANN have differed runoff simulation abilities in different climate zones, with low stability, and their simulation abilities are better in low latitude climate zones than in high latitude climate zones.

美国不同气候区小流域多源降水产品径流模拟性能

不同气候带降水资料产品的水文应用存在不确定性。本文以NOAA-CPC-US降水数据为参考，对美国不同气候带的PERSIANN、GPM-IMERG、StageIV雷达和气候模式ERA5等卫星降水数据产品的精度进行了评价。结果表明，StageIV在不同气候带的估算精度最高，其次是GPM-IMERG、PERSIANN和ERA5数值模式。利用这些数据产品驱动CREST分布式水文模型，评估其径流模拟效果。StageIV和NOAA-CPC-US在不同气候带的径流模拟中效果较好，满足径流模拟。GPM-IMERG和PERSIANN在不同气候带的径流模拟能力存在差异，稳定性较低，低纬度气候带的模拟能力优于高纬度气候带。

期刊介绍： IJEP provides an international forum in the field of environment and pollution and addresses early and medium-term challenges involving scientific prediction, modelling and assessment. It focuses on ground-breaking research in the science of environmental pollution, at the early scientific stage. It is one of three key journals which together offer complete coverage of environmental issues: IJETM focuses on technical/engineering, policy and management solutions for environmental problems, and IJGEnvI focuses on future, longer-term environmental scenarios, ecological economics, climate change and biodiversity.
