noaa_gefs_download_downscale: Download NOAA GEFS Forecasts

In rqthomas/noaaGEFSpoint: Downloads And Temporally Downscales NOAA GEFS 6-hr Forecasts for a Point Location

Description

Downloads a set of NOAA Global Ensemble Forecast System (GEFS) forecasts for a set of point locations or spatial ranges, downscaling them in time if requested.

Usage

noaa_gefs_download_downscale(
  site_list,
  lat_list,
  lon_list,
  output_directory,
  forecast_time = NA,
  forecast_date = NA,
  downscale = FALSE,
  debias = FALSE,
  debias_coefficients = NULL,
  run_parallel = FALSE,
  num_cores = 1,
  method = "point",
  overwrite = FALSE,
  read_from_path = FALSE,
  grid_name = "neon",
  process_specific_date = NA,
  process_specific_cycle = NA,
  delete_bad_files = TRUE,
  write_intermediate_ncdf = TRUE
)

Arguments

site_list	Vector of site codes, e.g. "NOAA", used in directory and file name generation.
lat_list	Vector or range of latitudes to be downloaded (see details).
lon_list	Vector or range of longitudes to be downloaded (see details).
output_directory	Path: directory where the model output will be saved.
forecast_time	The 'hour' of the requested forecast, one of "00", "06", "12", or "18" (see details). If omitted all times will be downloaded.
forecast_date	The date, or coercible string, of the requested forecast. ((Defaults to the most recent date.))
downscale	Logical specifying whether to downscale from 6-hr to 1-hr data.
debias	Logical specifying whether weather data should be adjusted for a bias verses the nearest forecast point.
debias_coefficients	If debias = TRUE, a data frame of debasing parameter value lists (see details).
run_parallel	Logical: whether to run on multiple cores.
num_cores	Integer: number of cores used if run_parallel = TRUE.
method	Character string indicating the download method, either "point" or "grid".
overwrite	Logical stating whether to overwrite any existing output files.
read_from_path	Point mode only:
grid_name	Grid mode only: a short grid name used in directory and file name generation.
process_specific_date	Grid mode only: A date, or coercible string, specifying specific date(s) within the forecast to extract. If omitted all dates will be downloaded.
process_specific_cycle	Grid mode only: A vector of forecast times ("00", "06", "12", or "18" hours), to extract. If omitted all cycles will be processed.
delete_bad_files	Grid mode only: Logical: delete bad files?
write_intermediate_ncdf	Grid mode only: Logical: retain the intermediate netCDF files created during processing?

Value

None
