drought4R

A drought assessment package for the climate4R Framework for climate data access and analysis.

This package is a wrapper to the R package SPEI (Beguería and Serrano 2017), tailored to its usage with large climate model datasets within climate4R. It also includes new routines for daily evapotranspiration estimation and calibrated Thornwaite's method, as used by Pereira and Pruitt (2004, DOI:10.1016/j.agwat.2003.11.003).

Installation

The latest stable release can be installed using install_github from package devtools (Wickham et al. 2018):

devtools::install_github("SantanderMetGroup/drought4R")

Worked examples

A worked example showing how to compute bias-corrected SPEI projections using Euro-CORDEX data from the User Data Gateway is available.
