List of nearby synop stations for a defined geographical location

Returns a data frame of meteorological stations with their coordinates and distance from a given location based on the ogimet webpage. The returned list is valid only for a given day.

nearest_stations_ogimet(
  country = "United Kingdom",
  date = Sys.Date(),
  add_map = FALSE,
  point = c(2, 50),
  no_of_stations = 10,
  allow_failure = TRUE,
  ...
)

Arguments

country: country name; for more than two words they need to be seperated with a plus character (e.g., "United+Kingdom"). It is possible to provide more than one country combined into a vector
date: optionally, a day when measurements were done in all available locations; current Sys.Date used by default
add_map: logical - whether to draw a map for a returned data frame (requires maps/mapdata packages)
point: a vector of two coordinates (longitude, latitude) for a point we want to find nearest stations to (e.g. c(0, 0))
no_of_stations: how many nearest stations will be returned from the given geographical coordinates
allow_failure: logical - whether to proceed or stop on failure. By default set to TRUE (i.e. don't stop on error). For debugging purposes change to FALSE
...: extra arguments to be provided to the graphics::plot() function (only if add_map = TRUE)

Value

A data.frame with number of nearest station according to given point columns describing stations parameters (e.g. ID station, distance from point in km, geographic coordinates, etc.). Each row represent a measurement, each station which has a measurements on selected date. If add_map = TRUE additional map of downloaded data is added.
