Wind rose for a range of days

Plots a wind rose showing wind speed and direction at a station over a period of days.

Usage

windrose_days(
  station,
  start = "2000-12-01",
  end = "2000-12-31",
  n_directions = 8,
  n_speeds = 5,
  speed_cuts = NA,
  col_pal = "GnBu",
  calm_wind = 0,
  legend_title = "Wind speed (m/s)",
  verbose = FALSE
)

Arguments

station

A character vector of station identifiers (see aemet_stations()) or "all" for all stations.

start

A character string containing the start date in YYYY-MM-DD format.

end

A character string containing the end date in YYYY-MM-DD format.

n_directions

The number of direction bins to plot (petals on the rose). Valid values are 4, 8 or 16.

n_speeds

The number of equally spaced wind speed bins to plot when speed_cuts is NA. Defaults to 5.

speed_cuts

A numeric vector with the cut points for the wind speed intervals, or NA (default).

col_pal

A character string specifying the hcl.pals() color palette to be used for plotting.

calm_wind

The upper wind speed limit considered calm. Defaults to 0.

legend_title

A character string or expression for the legend title.

verbose

A logical value. If TRUE, displays information about the exchange between the client and server.

Value

A ggplot2 object. See help("ggplot2").

API key

Queries to the AEMET OpenData API require an API key. Use aemet_api_key() to set it globally. Query timeout can be controlled with options(climaemet_timeout = 60) (default value). See httr2::req_timeout() for details.
