Description

Read NetCDF File

Usage

rfile(
  file,
  field,
  ...,
  navals = NA,
  lonmin = NA,
  lonmax = NA,
  latmin = NA,
  latmax = NA,
  zstart = 1,
  zcount = -1,
  tstart = 1,
  tcount = -1
)

Arguments

file	A character string specifying the NetCDF file location
field	A character string specifying the field to be read
...	An arbitrary number of character strings specifying additional fields to be read
navals	A float specifying NA values
lonmin	A float specifying longitude to start reading (optional)
lonmax	A float specifying longitude to stop reading (optional)
latmin	A float specifying latitude to start reading (optional)
latmax	A float specifying latitude to stop reading (optional)
zstart	An integer specifying first level to read (default: 1)
zcount	An integer specifying number of levels to read (default: -1)
tstart	An integer specifying first time-steps to read (default: 1)
tcount	An integer specifying number of time-steps to read (default: -1)

Examples

library(zeallot) # Need this to unpack data from rfile

# Read an entire field
c(lons, lats, APVTURBT)%<-%rfile("/net/thermo/atmosdyn2/atroman/stingjet/20140211_12/tra/APV12_20140212_07.nc","APVTURBT")

# Only read a specific subset of field
c(lons,lats,PV)%<-%rfile("/net/thermo/atmosdyn/atroman/phd/MAR18/cdf/S20180302_21","PV",lonmin=-60,lonmax=-20,latmin=46,latmax=86,zstart=2,zcount=2)
