paleoclim {rpaleoclim}

Retrieve data from PaleoClim

Description

Downloads data from PaleoClim (http://www.paleoclim.org) and loads it into R as a SpatRaster object.

Usage

paleoclim(
  period = c("lh", "mh", "eh", "yds", "ba", "hs1", "lig", "mis19", "mpwp", "m2", "cur",
    "lgm"),
  resolution = c("10m", "5m", "2_5m", "30s"),
  region = NULL,
  as = c("terra", "raster"),
  skip_cache = FALSE,
  cache_path = fs::path_temp(),
  quiet = FALSE
)

Arguments

period

Character. Time period to retrieve.

resolution

Character. Resolution to retrieve.

region

SpatExtent object or object that can be coerced to SpatExtent (see terra::ext()), describing the region to be retrieved. If NULL, defaults to the whole globe.

as

Character. as = "raster" returns a RasterStack object (see raster::stack()) instead of the default raster from the terra package. It is provided for backwards compatibility and will be removed in future versions. Requires the raster package.

skip_cache

Logical. If TRUE, cached data will be ignored.

cache_path

Logical. Path to directory where downloaded files should be saved. Defaults to R's temporary directory.

quiet

Logical. If TRUE, suppresses messages and download progress information.

Details

See http://www.paleoclim.org for details of the datasets and codings. Data at 30s resolution is only available for 'cur' and 'lgm'.

By default, paleoclim() will read previously downloaded files in R's temporary directory if available. Use skip_cache = TRUE to override this. cache_path can also be set to another directory. This can be useful if you want to reuse downloaded data between sessions.

Value

SpatRaster object (see terra::rast()) with each bioclimatic variable as a separate named layer.

Examples

paleoclim("lh", "10m")
