In MazamaScience/RAWSmet: Download and Process data from Remote Automatic Weather Stations

Load multiple FW13 RAWS timeseries objects from a local directory

Description

Loads FW13 station metadata and data from the rawsDataDir. If the data is not in this directory, this will download and save the data.

Usage

cefa_loadMultiple(
  nwsIDs = NULL,
  meta = NULL,
  newDownload = NA,
  baseUrl = "https://cefa.dri.edu/raws/fw13/",
  verbose = TRUE
)

Arguments

nwsIDs	Vector of NWS RAWS station identifiers.
meta	Tibble of FW13 station metadata.
newDownload	Logical flag stating whether or not to download and override existing data.
baseUrl	Base URL for data queries.
verbose	Logical flag controlling detailed progress statements.

Value

List of timeseries objects each containing 'meta' and 'data'.

Note

The 'newDownload' parameter has three possible settings:

• NA – Download data if it is not found in rawsDataDir

• TRUE – Always download data, overwriting existing data in rawsDataDir. This is useful for updating data files with more recent data.

• FALSE – Never download data. This is useful when working with wrcc_loadMultiple and archival data to avoid continually requesting data for stations which have no data over a particular time period.
