This function creates a single raster of persistent refugia for an ESM of interest, over a user-specified time period.
Arguments
- esm
Character. ESM model to use. Choose from
ens
,gfdltv
,hadtv
,ipsltv
.- yr_range
Vector of integers. Time period.
- persist_thresh
Integer. Temporal threshold (%) used for defining annual refugia. Choose either 50 (liberal) or 95% (conservative).
- save_path
Character. Directory to save output to. Optional, set to NULL if not needed.
Value
Produces a terra::rast()
object of persistent refugia (%), for the ESM specified.
Examples
persist_refugia <- build_persist(esm = "ens", yr_range = 2070:2099,
persist_thresh = 50, save_path = NULL)
