¢º Product Description
NWP products are based on the direct model output of the KMA(Korea Meteorological Administration)¡¯s operational global model - GDAPS(Global Data Assimilation and Prediction System) based on UM(Unified Model from UK Met office) with about 25 km horizontal resolution and 70 vertical layers (model top- 80km).
