Creata a NetCDF file with the surface mean

Description

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

Usage

extract_mean(
  filelist,
  variable = "o3",
  field = "4d",
  prefix = "mean",
  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(), "MEAN"))
folder <- system.file("extdata",package="hackWRF")
wrf_file <- paste0(folder,"/wrf.day1.o3.nc")
extract_mean(filelist = wrf_file,prefix = paste0(file.path(tempdir(),"MEAN"),'/mean'))
