wrf_rast: Creates SpatRaster object from wrf file

Description

Creates a SpatRaster (terra R-package) object from a variable from wrf file (or another compatible NetCDF)

Usage

wrf_rast(
  file = file.choose(),
  name = NA,
  map,
  level = 1,
  times,
  latlon = FALSE,
  method = "bilinear",
  as_polygons = FALSE,
  flip_h = FALSE,
  flip_v = FALSE,
  verbose = FALSE,
  ...
)

Value

SpatRaster object (terra package)

Arguments

file

wrf file

name

variable name

map

(optional) file with lat-lon variables and grid information

level

only for 4d data, numeric, default is 1 for surface (include all times)

times

only for 4d data, numeric, set to select time instead of levels (include all levels)

latlon

logical (default is FALSE), set TRUE project the output to "+proj=longlat +datum=WGS84 +no_defs"

method

method passed to terra::projection, default is bilinear

as_polygons

logical, true to return a SpatVector instead of SpatRaster

flip_h

horizontal flip (by rows)

flip_v

vertical flip (by cols)

verbose

display additional information

...

extra arguments passed to ncdf4::ncvar_get

Examples

{

wrf <- paste(system.file("extdata", package = "eva3dm"),
                         "/wrfinput_d01", sep="")

r <- wrf_rast(file=wrf, name='XLAT')

plot_rast(r)
