I have noticed that the KMA-UM global model introduced about two years ago is no longer available in dropdown list. Have you removed it? It should be available, since it is a global model that provides forecasts up to 10 days, compared to the ICON model that has forecasts only up to 7 days.
Elias Savolainen This model has been discontinued and is no longer provided by the Korea Meteorological Administration. ECMWF is a similar alternative.
