On the use of satellite, gauge, and reanalysis precipitation products for drought studies
Cleaning Jet Precipitation is a critical variable to monitor and predict meteorological drought.The WMO recommended standardized precipitation index (SPI) is calculated from gauge (i.e.GPCC), satellite-gauge (GPCP, CHIRPS), reanalysis (i.e.ERA-Interim, and MERRA-2), and satellite-gauge-reanalysis (i.e.MSWEP) over the global domain.Measured differen
