In this study, we conduct a comprehensive evaluation of three Satellite-based Precipitation Products (SPPs): Integrated Multi\u2013satellitE Retrievals for GPM (IMERG) Final run V6, Soil Moisture to Rain (SM2RAIN)-Advanced SCATterometer (ASCAT) V1.5, and Multi-Source Weighted-Ensemble Precipitation (MSWEP) V2.2 for a subbasin of the Mekong River Basin (MRB). The study area of the Srepok River basin (SRB) represents the Central Highland sub-climatic zone in Vietnam under the impacts of newly built reservoirs during 2001\u20132018. In this study, our evaluation was performed using the Rainfall Assessment Framework (RAF) with two separated parts: (1) an intercomparison of rainfall characteristics between rain gauges and SPPs; and (2) a hydrological comparison of simulated streamflow driven by SPPs and rain gauges. Several key findings are: (1) IMERGF-V6 shows the highest performance compared to other SPP products, followed by SM2RAIN-ASCAT V1.5 and MSWEP V2.2 over assessments in the RAF framework; (2) MSWEP V2.2 shows discrepancies during the dry and wet seasons, exhibiting very low correlation compared to rain gauges when the precipitation intensity is greater than 15 mm\/day; (3) SM2RAIN\u2013ASCAT V1.5 is ranked as the second best SPP, after IMERGF-V6, and shows good streamflow simulation, but overestimates the wet seasonal rainfall and underestimates the dry seasonal rainfall, especially when the precipitation intensity is greater than 20 mm\/day, suggesting the need for a recalibration and validation of its algorithm; (4) SM2RAIN-ASCAT had the lowest bias score during the dry season, indicating the product\u2019s usefulness for trend analysis and drought detection; and (5) RAF shows good performance to evaluate the performance of SPPs under the impacts of reservoirs, indicating a good framework for use in other similar studies. The results of this study are the first to reveal the performance of MSWEP V2.2 and SM2RAIN-ASCAT V1.5. Additionally, this study proposes a new rainfall assessment framework for a Vietnam basin which could support future studies when selecting suitable products for input into hydrological model simulations in similar regions.<\/jats:p>","DOI":"10.3390\/rs15041030","type":"journal-article","created":{"date-parts":[[2023,2,14]],"date-time":"2023-02-14T01:41:06Z","timestamp":1676338866000},"page":"1030","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":69,"title":["Quantification of Gridded Precipitation Products for the Streamflow Simulation on the Mekong River Basin Using Rainfall Assessment Framework: A Case Study for the Srepok River Subbasin, Central Highland Vietnam"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8478-5893","authenticated-orcid":false,"given":"Thanh-Nhan-Duc","family":"Tran","sequence":"first","affiliation":[{"name":"Department of Engineering Systems and Environment, University of Virginia, Charlottesville, VA 22903, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6292-5349","authenticated-orcid":false,"given":"Binh Quang","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Faculty of Water Resources Engineering, The University of Danang\u2014University of Science and Technology, Da Nang 550000, Vietnam"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5546-2518","authenticated-orcid":false,"given":"Runze","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Engineering Systems and Environment, University of Virginia, Charlottesville, VA 22903, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2890-4867","authenticated-orcid":false,"given":"Aashutosh","family":"Aryal","sequence":"additional","affiliation":[{"name":"Department of Engineering Systems and Environment, University of Virginia, Charlottesville, VA 22903, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3420-6811","authenticated-orcid":false,"given":"Maria","family":"Grodzka-\u0141ukaszewska","sequence":"additional","affiliation":[{"name":"Faculty of Building Services, Hydro and Environmental Engineering, Warsaw University of Technology, 00-653 Warszawa, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1830-104X","authenticated-orcid":false,"given":"Grzegorz","family":"Sinicyn","sequence":"additional","affiliation":[{"name":"Faculty of Building Services, Hydro and Environmental Engineering, Warsaw University of Technology, 00-653 Warszawa, Poland"}]},{"given":"Venkataraman","family":"Lakshmi","sequence":"additional","affiliation":[{"name":"Department of Engineering Systems and Environment, University of Virginia, Charlottesville, VA 22903, USA"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,13]]},"reference":[{"key":"ref_1","first-page":"625","article-title":"Global-Scale Evaluation of 22 Precipitation Datasets Using Gauge Observations and Hydrological Modeling","volume":"21","author":"Beck","year":"2020","journal-title":"Hydrol.
