To support the 2018 Winter Games with accurate weather predictions, the Korea Meteorological Administration (KMA) initiated the International Collaborative Experiments for PyeongChang Olympic and Paralympic winter games (ICE-POP 2018) project. ICE-POP 2018 is a component of the WMO’s World Weather Research Program (WWRP) Research and Development and Forecast Demonstration Projects (RDP/FDP) and involves observation, nowcasting, numerical weather prediction, and verification activities. An array of radars, lidars, precipitation and cloud physics sensors were deployed around the venues in support of experimental nowcasting and very short-range forecasting products. In addition a mobile observation system, research ship and research aircraft were deployed to fill observation gaps. All experimental products were used and evaluated in various scenarios during the Winter Games and will undergo careful verification in the months and years to come.
