get_am_cell_zones_grd()A terra raster layer with 1 layer:
half degree cell identifier (integer) from am_cell_zones
Cannot simply load this as an available dataset into the R package since
terra::rast() only loads a pointer to raster file, not its contents.
am_cell_zones_grd <- get_am_cell_zones_grd()
