obs_load_ncdf

NetCDF list of var and attributes

Usage

obs_load_ncdf(
  ncname,
  vars = NULL,
  grps = NULL,
  dims = TRUE,
  useoldfoot = FALSE,
  attribs = "Conventions",
  var.attribs = NULL,
  gz = FALSE,
  tmpdir = tempdir(),
  tmpfile = tempfile("load.ncdf4", tmpdir = tmpdir),
  clean = TRUE,
  lowercase = FALSE,
  gsubdot = FALSE,
  verbose = FALSE
)

Arguments

ncname

pathname of NetCDF4 file

vars

specify variables to retrieve otherwise all are returned (NOTE: '/' indicates only return root group)

grps

groups

dims

return variable dimensions TRUE/FALSE

useoldfoot

old footprints have dim order: lat,lon,time but new footprints (CF-1.6 convention and on) have dim order: lon,lat,time; this option flips lat/lon dim order of returned footprints for backwards compatibility; TRUE => flips new footprints to old convention; FALSE => flips old footprints to new convention

attribs

array of names of global file attributes to return (NOTE: this is for backwards compatibility - current version automatically returns all global file attributes)

var.attribs

array of names of variable attributes to return (NOTE: this is for backwards compatibility - current version automatically returns all attributes for variables and dimensions)

gz

netCDF file is gzipped. Note that .nc may be already compressed.

tmpdir

temporary directory to unzip netCDF file

tmpfile

temporary unzipped netCDF file name

clean

remove temporary file after processing

lowercase

return all list names in lowercase

gsubdot

substitute '_' with '.' in all list variable names

verbose

logical, to show more messages

Value

list of NetCDF vars and attributes
