Download future climate data for Central America

ca_future_worldclim.Rd

This function allows you to parse from worldclim version 2.1 future climatic files for Central America.

This function is a wrapper of the future_worldclim2 function from the itsdm package.

Usage

ca_future_worldclim(var, res, gcm, ssp, interval, path, return_stack = TRUE)

Arguments

var

(character) The option for the variable to download. Should be one of tmin, tmax, prec, bioc. The default is tmin.

res

(numeric) The option for the resolution of image to download. Should be one of 0.5, 2.5, 5, 10. The default is 10.

gcm

(character) The option for global climate models. Check https://www.worldclim.org for all available GCM.

ssp

(character) The option for Shared Socio-economic Pathways. Should be one of "ssp126", "ssp245", "ssp370", "ssp585". The default is "ssp585".

interval

(character) The option for time interval. Should be one of "2021-2040", "2041-2060", "2061-2080", "2081-2100". The default is "2021-2040".

path

(character) The path to save the downloaded imagery. If NULL, it would use the current working directory. The default is NULL.

return_stack

(logical) if TRUE, stack the imagery together and return. If the area is large and resolution is high, it is better not to stack them. The default is TRUE.

Value

if return_stack is TRUE, the images would be returned as a stars. Otherwise, nothing to return, but the user would receive a message of where the images are.

Note

If it fails due to slow internet, try to set a larger timeout option, e.g., using `options(timeout = 1e3)`.
