PaleoClim is a set of free,high resolution paleoclimate surfaces covering the whole globe. Itincludes data on surface temperature, precipitation and the standardbioclimatic variables commonly used in ecological modelling, derivedfrom the HadCM3 general circulation model and downscaled to a spatialresolution of up to 2.5 minutes.
This package provides a simple interface for downloading PaleoClimdata in R, with support for caching and filtering retrieved data byperiod, resolution, and geographic extent.
Installation
You can install the latest release of rpaleoclim fromCRAN with:
install.packages("rpaleoclim")Or the development version fromGitHub using theremotespackage:
remotes::install_github("joeroe/rpaleoclim")Usage
The package includes two functions,paleoclim() andload_paleoclim().paleoclim() downloads datafrom PaleoClim with the desired period and resolution and reads it intoR as aSpatRasterobject.
library("rpaleoclim")library("terra")# For plottingpaleoclim("lh","10m")|>plot()
By default, files from PaleoClim are cached in a local temporarydirectory to avoid repeated download of the same data.load_paleoclim() reads local PaleoClim files (in.zip format) in the same way.
For further details see theintroductionto rpaleoclim vignette (vignette("rpaleoclim")).
