This software facilitates the calculation of various drought indices including SPI, DI, PN, RAI, EDI, CZI, MCZI, and ZSI. These indices help in determining drought conditions and their intensity based on standardized precipitation and rainfall anomaly.

Drought indices are commonly used for detecting the onset and end of droughts and indicating changes over different timescales. Therefore, it is essential for users to be able to calculate these indices easily through software. The RDIT software can perform and run eight rain-based drought indices in a user-friendly tool. Additionally, the software can help users interpret the results by plotting various graphs.
To advance the understanding of monitoring and investigating droughts, it is crucial to assess drought frequency and severity. Every drought is distinguished by its duration, severity, and interval. The onset, end, and severity of the drought are important features to monitor. Determining the severity of drought can be a daunting process, but it is crucial for drought analysis. In the RDIT software, users can easily calculate and plot the severity of the drought, making it a valuable tool for drought monitoring and analysis.
