Gives predictions on future values for the choosen phase. Prediction are from multiple models (GFDL-ESM4, IPSL-CM6A-LR, MPI-ESM1-2-HR, MRI-ESM2-0, UKESM1-0-LL). Creates folder for each model and a folder with mean of this five models. Monthly variables are average temperatures, min temperatures, max temperatures, precipitation, potential evapotranspiration with Thornthwaite formula. Others variables are climatic water deficit with Thornthwaite, number of dry month with Thornthwaite and 19 bio variables (more information in chelsa documentation).

Arguments

extent_latlon

vector. First output of get_aoi_extent() function.

extent_proj

vector. Second output of get_aoi_extent() function.

EPSG

int. to consider for this country/area.

destination

character. absolute path where to download files like here() output.

resol

int. Resolution. If in meters, recommended resolutions are 250m, 500m, 1km, 2km or 5km. The resolution needs to be carefully chosen. If set too small (e.g. < 250m), raster file will be too big to fit in memory and R will crash. Default is 1km.

phase

character. Must be in c("2041-2070", "2071-2100") match to years to download, default is "2071-2100".

GCM

character. Global Climatic Models considered. Must be in c("GFDL-ESM4", "IPSL-CM6A-LR", "MPI-ESM1-2-HR", "MRI-ESM2-0", "UKESM1-0-LL"). By default climate simulated by the five GCMs are downloaded.

SSP

character or int. Scenario specifier must be in c(126, 370, 585). Corresponding to the the Shared Socio-economic Pathways you want to download, default is 585 for SSP5-RCP8.5 climate as simulated by the GCMs.

rm_download

boolean. If TRUE remove download files and folders. Keep only future_chelsa.tif in data_raw folder, default is FALSE.

Value

character. absolute path to future_chelsa.tif.
