Windrose (speed/direction) diagram of a station over a period of days

Description

Plot a windrose showing the wind speed and direction for 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	Character string with station identifier code(s) (see aemet_stations()) or "all" for all the stations.
start	Character string with the start date (format: "YYYY-MM-DD").
end	Character string with the end date (format: "YYYY-MM-DD").
n_directions	Numeric value with the number of direction bins to plot (petals on the rose). Valid values are 4, 8 or 16.
n_speeds	Numeric value with the number of equally spaced wind speed bins to plot. This is used if speed_cuts is NA (default 5).
speed_cuts	Numeric vector with the cut points for the wind speed intervals, or NA (default).
col_pal	Character string indicating the name of the hcl.pals() color palette to be used for plotting.
calm_wind	Numeric value with the upper limit for wind speed that is considered calm (default 0).
legend_title	Character string to be used for the legend title.
verbose	Logical. If TRUE, provides information about the flow of information between the client and server.

Value

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

API key

You need to set your API key globally using aemet_api_key(). Query timeout can be controlled with options(climaemet_timeout = 60) (default value). See httr2::req_timeout() for details.
