In eva3dm: Evaluation of 3D Meteorological and Air Quality Models

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,
  ...
)

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

Value

SpatRaster object (terra package)

Examples

{

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

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

plot_rast(r)
}
