    摘要:

    从IMERG、DPR和水文模拟3方面综述了GPM降水产品的评估工作。GPM降水产品在复杂地形和高海拔地区均表现不佳,甚至出现不可靠的情况,还存在明显的季节差异性,主要表现为夏秋两季的表现较好,春冬两季表现相对较差。指出GPM对微量降水、固态降水和极端降水的观测还需进一步的完善,未来的卫星降水评估工作应从传感器层面上展开。

    Abstract:

    This paper reviews the assessments on global precipitation measurement(GPM)precipitation products from three aspects of integrated multi-satellite retrievals for global precipitation measurement(IMERG), dual-frequency precipitation radar(DPR)and hydrologic simulation. The results show that the performance of GPM precipitation products is poor or even unreliable in complex terrain and high elevation areas, and there are significant seasonal differences that the performances of GPM precipitation products are good in summer and autumn, while relatively poor in spring and winter. The author of this paper believed that the observation to drizzle, heavy rainfall and solid precipitation by GPM should be improved, and the future assessment on satellite precipitation products should be carried out at sensor level.
