noaa_gefs_grid_process_downscale: Extract and downscale points from a NOAA GEFS Forecast

In FLARE-forecast/Rnoaa4cast: Downloads And Temporally Downscales NOAA GEFS 6-hr Forecasts for a Point Location

Extract and downscale points from a NOAA GEFS Forecast

Description

This function extracts a set of point location forecasts from a previously downloaded gridded NOAA Global Ensemble Forecast System (GEFS) forecast and optionally temporally downscales them.

Usage

noaa_gefs_grid_process_downscale(
  lat_list,
  lon_list,
  site_list,
  downscale,
  debias = FALSE,
  overwrite,
  model_name,
  model_name_ds,
  model_name_ds_debias,
  model_name_raw,
  debias_coefficients = NULL,
  num_cores,
  output_directory,
  reprocess = FALSE,
  write_intermediate_ncdf = TRUE,
  process_specific_date = NA,
  process_specific_cycle = NA,
  delete_bad_files = TRUE,
  grid_name = "neon",
  s3_mode = FALSE,
  bucket = NULL
)

Arguments

lat_list	Vector or range of latitudes to be downloaded (see details).
lon_list	Vector or range of longitudes to be downloaded (see details).
site_list	Vector of site codes, e.g. "NOAA", used in directory and file name generation.
downscale	Logical specifying whether to downscale from 6-hr to 1-hr data.
overwrite	Logical stating whether to overwrite any existing output files
model_name	Directory name for the 6-hr forecast, this will be used in directory and file name generation.
model_name_ds	Directory name for downscaled 1-hr forecasts, this will be used in directory and file name generation.
model_name_ds_debias	Directory name for downscaled and diabiased forecasts, this will be used in directory and file name generation.
debias_coefficients	Data frame containing debasing parameter values.
num_cores	The number of processor cores to run in parrallel on.
output_directory	Path: directory where the model output will be saved.
reprocess	Logical: if true re-extract dates that were previously processed.
write_intermediate_ncdf	Logical: retain the intermediate netCDF files created during processing?
process_specific_date	A date, or coercible string, specifying specific date(s) to extract. If omitted all dates will be processed.
process_specific_cycle	A vector of forecast times ("00", "06", "12", or "18" hours), to extract. If omitted all cycles will be processed.
delete_bad_files	Logical: delete bad files?
grid_name	A short grid name used in directory and file name generation.
s3_mode	Logical: save the forecast to a Amazon S3 bucket rather than locally.
bucket	If s3_mode = TRUE, the S3 bucket name to save to.
