Slovenia Weather Observations: Synoptic Stations, Hourly (ARSO)

arsoweather/synoptic-observations

The latest hourly weather observations from ARSO's synoptic stations across Slovenia (about 20 stations, in English): temperature, humidity, dew point, wind direction and speed, air pressure, visibility, cloud cover and present weather where the station reports them, with station name, position and altitude. Takes no input. Slovenian Environment Agency data, reshaped from XML into JSON and served by Eden Engine; not an official ARSO product.
