Download CRUNCEP data — download.CRUNCEP • PEcAn.data.atmosphere

Download and convert to CF CRUNCEP single grid point from MSTIMIP server using OPENDAP interface

Usage

download.CRUNCEP(
  outfolder,
  start_date,
  end_date,
  lat.in,
  lon.in,
  overwrite = FALSE,
  verbose = FALSE,
  maxErrors = 10,
  sleep = 2,
  method = "ncss",
  ...
)

Arguments

outfolder: Directory where results should be written
start_date, end_date: Range of years to retrieve. Format is YYYY-MM-DD, but only the year portion is used and the resulting files always contain a full year of data.
lat.in: site latitude in decimal degrees
lon.in: site longitude in decimal degrees
overwrite: logical. Download a fresh version even if a local file with the same name already exists?
verbose: logical. Passed on to ncvar_def and nc_create to control printing of debug info
maxErrors: Maximum times to re-try following an error accessing netCDF data through THREDDS
sleep: Wait time between attempts following a THREDDS or other error
method: (string) Data access method. `opendap` (default) attempts to directly access files via OpenDAP. `ncss` (NetCDF subset) subsets the file on the server, downloads the subsetted file to `tempfile` and then reads it locally. `opendap` is faster when it works, but often fails because of server issues. `ncss` can be much slower, but is more reliable.
...: Other arguments, currently ignored
