In Schuch666/hackWRF: Functions to Work with WRF, NetCDF and Model Evaluation

Creata a NetCDF file with the surface maximum

Description

Read and calculate the maximum value of a variable from a list of wrf output files.

Usage

extract_max(
  filelist,
  variable = "o3",
  field = "4d",
  prefix = "max",
  units = "ppmv",
  meta = T,
  filename,
  verbose = TRUE
)

Arguments

filelist	list of files to be read
variable	variable name
field	'4d' (default), '3d', '2d' or '2dz' see notes
prefix	to output file, defolt is serie
units	units on netcdf file (default is ppmv)
meta	use Times, XLONG and XLAT data (only work with 2d variable for file)
filename	name for the file, in this case prefix is not used
verbose	display additional information

Note

The field argument '4d' / '2dz' is used to read a 4d/3d variable droping the 3rd dimention (z).

Examples

dir.create(file.path(tempdir(), "MAX"))
folder <- system.file("extdata",package="hackWRF")
wrf_file <- paste0(folder,"/wrf.day1.o3.nc")
extract_max(filelist = wrf_file,prefix = paste0(file.path(tempdir(),"MAX"),'/mean'))
