SPEI Calculator

Authors: Beguería, Santiago; Vicente Serrano, Sergio M.;

SPEI Calculator

Abstract

[ES] * Objetivos: Calcular series temporales del Índice Estandarizado de Precipitación-Evapotranspiración (SPEI, en sus siglas inglesas). * Características Técnicas: El programa se ejecuta desde el intérprete de comandos de Windows (consola de sistema). A partir de un archivo de datos de precipitación y temperatura media mensuales y la localización (coordenadas) del observatorio, el programa calcula el índice SPEI acumulado al intervalo temporal en meses elegido por el usuario, generando un nuevo archivo con la serie temporal del índice. Es posible crear de manera sencilla archivos de procesamiento por lotes (batch scripts) que permiten el cálculo del índice SPEI para una serie de observatorios o para distintos intervalos acumulados. *ADVERTENCIA: El desarrollo de este software ha sido interrumpido y reemplazado por la librería SPEI para R: http://cran.r-project.org/web/packages/SPEI/index.html.

[EN] *Objectives: The program calculates time series of the Standardised Precipitation-Evapotransporation Index (SPEI). *Technical Characteristics: The program is executed from the Windows console. From an input data file containing monthly time series of precipitation and mean temperature, plus the geographic coordinates of the observatory, the program computes the SPEI accumulated at the time interval specified by the user, and generates a new data file with the SPEI time series. It is easy to create a batch script for automating the calculation of the SPEI over a large number of observatories or for several accumulated periods. *IMPORTANTE NOTICE: This software has been superseded by the SPEI package for R, which is currently the only development branch. Please, have a look at http://cran.r-project.org/web/packages/SPEI/index.html.
