We developed the “RDIT” (Rain-based Drought Indices Tool ) software application for calculating eight rain-based 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. You can calculate drought severity and plot graphs for your index.

The world is suffering from many natural disasters such as droughts due to climate change. We may need more research activities and monitoring this phenomena for preparing to counter measures on droughts. With appropriate tools we can achieve better result. One of this tools are drought indices, however calculating this indices are not easy for users and they need a user-friendly software application to calculating them. So, the “RDIT” tool can calculate and perform rain-based drought indices.

This software can calculate eight indices of meteorological drought. You can draw graphs and estimate severity, onset, and end of each period’s drought. Input and output data are in excel format file. For input data, RDIT is smart. It can assess your data and check blank cells and produce data for “null” cells. This software calculates 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), ZSI (Z-Score Index) in form of yearly, seasonally, monthly and moving average for 3, 6, 9, 12, 18, 24, 48 months. You can save graphs to image files.
