Download MERRA data

Usage

download.MERRA(
  outfolder,
  start_date,
  end_date,
  lat.in,
  lon.in,
  overwrite = FALSE,
  verbose = FALSE,
  ...
)

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
...: Not used – silently soak up extra arguments from `convert_input`, etc.
