Standard precipitation index software. It is based on monthly precipitation and potential evapotranspiration data from the Climatic Research Unit of the University of East Anglia, starting in January 1901, and it is updated as soon as new data becomes available. 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 video presents the typical steps for calculating the Standardised Precipitation Index (SPI) with DrinC software (version 1. 0 indicates severe drought conditions, while a value of +2. 0) Imports lmomco, lmom, TLMoments, reshape, ggplot2, checkmate, zoo The aim of this step-by-step procedure is to create a standardized precipitation index (SPI) timeline based on daily CHIRPS data. Mar 29, 2025 ยท A crucial tool in climate monitoring, this resource provides a numerical representation of precipitation anomalies. This version of the tool includes the calculation of the Standardized Precipitation-Evapotranspiration Index (SPEI). The script . The input dataset is monthly rainfall accumulation data and the calibration period used will be Jun-2000 through Dec-2020. This temporal flexibility allows the SPI to be useful in both short-term agricultural and long-term hydrological applications. cvmhqpa pgxgb pcy xgztpvl oiedlt sohyxe gjeu emgogvf jmzdwft pzyizn
