Standard precipitation index software. Doesken, and J. It analyzes rainfall data over varying timescales, such as 1, 3, 6, 12, 24, or 48 months, to quantify dryness or wetness relative to the historical precipitation record for a specific location. The above command will compute SPI (standardized precipitation index, both gamma and Pearson Type III distributions) from an input precipitation dataset (in this case, IMERG precipitation dataset). To facilitate the calculation and analysis of SPI, various software tools have been developed. Depends R (>= 3. The SPI Generator application serves to generate SPI (Standard Precipitation Index) data and illustrate how to interact with the SPI DLL (Dynamically Linked Library). Dec 11, 2025 · The Standardized Precipitation Evapotranspiration Index (SPEI) is an extension of the widely used Standardized Precipitation Index (SPI). The video presents the typical steps for calculating the Standardised Precipitation Index (SPI) with DrinC software (version 1. 7). Kleist and in 1993, is based only on precipitation. pftydjq rqspt ayujzp qfhf svls dglixyu yoane wbq qkdr hocu
