What is the used database in MDM (Meteorological Drought Monitoring) software?

The MDM software calculates rain-based meteorological drought indices, namely SPI (Standardized Precipitation Index), DI (deciles index), PN (Percent of Normal Index), RAI (Rainfall Anomaly Index), EDI (effective drought index), CZI (China-Z index), MCZI (modified CZI), and ZSI (Z-Score Index) in form of yearly, seasonally, monthly and moving average for 3, 6, 9, 12, 18, 24, and 48 months. There is a database of AgMERRA in this software that presents daily precipitation, since the eight indices just use precipitation data, so we’ve added precipitation data of AgMERRA. Based on the NASA Modern Era Retrospective Analysis for Research and Applications (MERRA) outputs (Rienecker et al., 2011), the AgMERRA global gridded climate dataset (0.25°×0.25° horizontal resolution; ~25 km) provided daily, high-resolution and continuous meteorological datasets for the period 1980–2010 and was advocated to be useful for agricultural and meteorological projects (Ruane et al., 2015).
