#' CMIP6 sample
#'
#' A small extract of model output and native grid ('gn') coordinates from CMIP6. Derived from
#' 'CMIP6/ssp245/intpp/intpp_Omon_MPI-ESM1-2-LR_ssp245_r1i1p1f1_gn_201501-203412.nc'.
#'
#' The [cmip6] object is a 'RasterBrick', defined by the raster package with three
#' layers: 'intpp', 'longitude', 'latitude'. The model data is primary organic carbon production 'intpp'.

#' World raster map
#'
#' A rasterized version of `wrld_simpl`, created by burning the country
#' polygon ID number into a one-degree world raster. (This is a very
#' out of date polygon data set used for example only).See code in
#' 'data-raw/worldll.R'.

#' World topography map
#'
#' A simplified version of 'Etopo2'. The Etopo2 data set was
#' reduced 20X to create this raster layer of global relief. See code
#' in 'data-raw/topo.R'.
