Evaluation and Hydrological Utility of the Latest GPM IMERG V5 and GSMaP V7 Precipitation Products over the Tibetan Plateau

Abstract: Satellite precipitation products provide alternative precipitation data in mountain areas. This study aimed to assess the performance of the latest Global Precipitation Measurement (GPM) Integrated Multi-satellite Retrievals for GPM (IMERG) version 5 (IMERG V5) and Global Satellite Mapping of Precipitation version 7 (GSMaP V7) products and their hydrological utilities over the Tibetan Plateau (TP). Here, two IMERG Final Run products (uncalibrated IMERG (IMERG-UC) and gauge-calibrated IMERG (IMEEG-C)) and two G… Show more

“…Here, a commonly used threshold of 1.0 mm/day was set to define the rain/no rain event, as suggested by many previous studies [47][48][49][50]. For more detailed description of above continuous statistical metrics and contingency table metrics, readers can refer to Yong et al [25] and Lu et al [30]. We need to point out that all metrics were calculated in the 0.25 • × 0.25 • grid boxes with at least one gauge in order to ensure more convincing results (gauge distribution shows in Figure 1a).…”

“…The question of the availability exists widely in the gauge-adjusted satellite precipitation products. For example, if someone want to use PERSIANN-CDR or GSMaP_Gauge data, they must wait~3 months or~3 days after observation, respectively [21,30].In some cases, the real-time availability precipitation data is more critical for applications like rainstorm monitoring and flash flood warning, and it does not seem practical to use the traditionally delayed gauge-adjusted satellite precipitation products [31,32]. Thus, it is important to reduce the error of satellite precipitation estimates as much as possible without jeopardizing its near-real-time availability.…”

“…GSMaP provides three sets of mainstream types of satellite precipitation data based on different sensor input sources and algorithms, namely near-real-time product GSMaP_NRT, standard research product GSMaP_MVK, and gauge-calibrated product GSMaP_Gauge. The original instantaneous precipitation rate is estimated by a variety of passive microwave (PMW) sensors, including GPM Microwave Imager (GMI), advanced microwave scanning radiometer 2 (AMSR2), TRMM Microwave Imager (TMI), special sensor microwave imager/sounder (SSMIS), advanced microwave sounding unit-A (AMSU-A), and microwave humidity sounder (MHS) [27]. GSMaP_NRT uses less PMW input streams and a forward-only cloud advection scheme [28].…”

“…The study by Lu et al [13] assesses the performance of the latest GPM Integrated Multi-satellite Retrievals (IMERG V5) and Global Satellite Mapping of Precipitation version 7 (GSMaP V7) products and their hydrological application over the Tibetan Plateau. Two IMERG Final Run products Martins Costa do Amaral et al [14] apply the Satellite Application Facility on Support to Operational Hydrology and Water Management (H-SAF) consolidated radar data processing to the X-band radar used in the CHUVA (Cloud Processes of the Main Precipitation Systems in Brazil: A Contribution to Cloud-Resolving Modeling and to the Global Precipitation Measurement) campaigns in Brazil.…”
