How can I get the MDM Software for Drought analysis?

You can download MDM by clicking on download in the Meteorological Drought Monitoring page. After you download, you can easily install it. In help menu you can open registration page and then register it online, freely.

A meteorological drought can be seen as a result of a precipitation shortage or which is defined as the lack of precipitation over a region for a period of time. It is usually region-specific because the atmospheric conditions in different areas are highly variable in space and time.

We developed the "MDM" (Meteorological Drought Monitoring) software application for calculating eight 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. Because using different drought indices at a given time can show drier or wetter than usual conditions (Smakhtin and Hughes, 2007), user-friendly software is a critical tool for calculating and comparing multiple locations, time periods, and data source influences efficiently.

The "MDM" software package currently bases calculations on two sources of data. The first is a synoptic station data file, which includes daily precipitation in excel format. The second one is a database of daily precipitation from AgMERRA, available for the Middle-East region. The user can click the map on the desired point in the package and calculate all indices for that 0.25 degree grid location. There is a complete help file in the package, which describes all setup steps.
