chelsa function

Climatologies at High resolution for the Earth Land Surface Areas (CHELSA)

The CHELSA data (Karger et al. 2017) consists of downscaled model output temperature and precipitation estimates at a horizontal resolution of 30 arc sec. The precipitation algorithm incorporates orographic predictors including wind fields, valley exposition, and boundary layer height, with a subsequent bias correction. The spatial resolution is about 1-arc second (~1km at the equator). This resource makes V2 available.

get_chelsa(years = 1979:2018)

Arguments

• years: A numeric vector of the years to make CHELSA monthly precipitation layers available for. Must be greater 1979, defaults to c(1979:2018).

Returns

A function that returns an sf footprint object.
