Function bulk downloads National Weather Service precipitation geotiff files

Description

Usage

downloadNWS(
  data_folder,
  overwrite_data = FALSE,
  stage3_filename = "nws_precip_mtd_YYYYMMDD.tif",
  stage4_filename = "nws_precip_mtd_YYYYMMDD_conus.tif",
  day_range = 1,
  month_range = 1:12,
  year_range = 2005:as.numeric(format(Sys.Date(), format = "%Y"))
)

Arguments

data_folder	parent directory for data to be deposited. If this does not exist, it will be created.
overwrite_data	TRUE/FALSE value indicating whether existing files should be overwritten. If TRUE, all data are downloaded fresh.
stage3_filename	example of a stage 3 filename. YYYYMMDD is a token that will be replaced with actual dates. Adjusting this can accommodate odd filenames (e.g., stage 3 2017; stage 4 2016) and download different data types (e.g., 1 day, last 180 days)
stage4_filename	example of a stage 4 filename. YYYYMMDD is a token that will be replaced with actual dates.
day_range	numeric range of days, used in identifying files to download. Default only downloads data from the first of the month.
month_range	numeric range of months, used in identifying files to download. Default downloads data from all months.
year_range	numeric range of years, used in identifying files to download. Default downloads data from all years (filtered by available Stage 3/Stage 4 data).
