Plot sun position and horizons from local terrain model, local surface model and regional digital terrain model with infos from the weather station.

Usage

plot_station_horizon_sun(stn = NULL, path = stn$path)

Arguments

stn

A SpatVector with station attributes from "get_metadata_frost"

path

A directory path defining where will be saved the plots, if path is NULL the plots are printed to the console

Value

Sun diagram with station metadata
