The International Collaborative Experiment for PyeongChang Olympic and Paralympics (ICE-POP) was held in South Korea in February 2018. NASA's GPM Ground Validation program assisted the Korean Meteorological Administration (KMA) and provided ground-based instruments for forecast and research studies before, during and after the 2018 Winter Olympic Games (February 9-25, 2018). The focus study period took place November 1, 2017 through March 17, 2018, but there are pre-and post-campaign data. Preparations for ICE-POP 2018 began in November 2016 when a Letter of Agreement (LOA) was concluded between NASA and KMA. ICE-POP provided GPM ground validation valuable data for researching frozen and mixed phase precipitation in complex terrain. GPM radars and ground instruments were used for both nowcasting and forecasting support during Olympics operations. More information about the ICE-POP campaign can be found at the ICE-POP Project Homepage.
