precipitation_chelsa: Calculate precipitation average based on CHELSA

Description

This functions allows to calculate averaged precipitation from the CHELSA downscaled precipitation layers. Based on user-selected years, monthly averages of precipitation are calculated.

Usage

calc_precipitation_chelsa(years = 1979:2018, engine = "extract")

Value

A function that returns an indicator tibble with variable precipitation and sum of precipitation (in mm/m^2) as value.

Arguments

years

A numeric vector indicating the years for which to calculate precipitation statistics.

engine

The preferred processing functions from either one of "zonal", "extract" or "exactextract" as character.
