Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS)

This resource is published by Funk et al. (2015) and represents a quasi-global (50°S-50°S) rainfall estimation at a monthly resolution starting with the year 1981 to the near-present. It has a spatial resolution of 0.05°. The data can be used to retrieve information on the amount of rainfall. Due to the availability of +30 years, anomaly detection and long-term average analysis is also possible. The routine will download the complete archive in order to support long-term average and anomaly calculations with respect to the 1981 - 2010 climate normal period. Thus no additional arguments need to be specified.

Usage

get_chirps(years = 1981:2020)

Arguments

years

A numeric vector of the years to download CHIRPS precipitation layers. Must be greater 1981, defaults to c(1981:2020).

Value

A function that returns an sf footprint object.
