Intercomparison of Global Satellite Mapping of Precipitation (GSMaP) using rain-gauge observations based on multiple temporal resolutions in Vietnam
The performance of the Global Satellite Mapping of Precipitation (GSMaP) data overVietnam during the period from March 2014 to October 2018 was analyzed by comparing three standard products, including the newest Standard version 7 (MVKv7), the Standard with Gauge-Calibration version 7 (GAUv7), and the Standard with Gauge-Calibration version 6 (GAUv6) at two temporal resolutions (daily and 6-hourly accumulated rainfall) in order to assess the importance of the rain-gauge calibration algorithm as well as to determine whether the upgraded version showed an improved performance over Vietnam. Besides, the effects of theelevation and estimation of GSMaP for several rainfall thresholds also were considered. The results suggested the potential applications of GSMaP MVKv7 for Highland Vietnam, GAUv6 and GAUv7 for other regions, and the utilization of GSMaP for heavy-rainfall cases. However, the argument about the better quality of GAU version 7 than version 6 is still controversial.
