KMA Space Weather Prediction Model (1/2) 4 KREAM -A cosmic radiation dose model KREAM(Korean Radiation Exposure Assessment Model for aviation route dose), is based on the GEANT4 particle transport model and real-time atmospheric model of NRLMSIS00 -Considering not only GCR(Galactic Cosmic Ray) but also SEP(Solar Energetic Proton) -KREAM can give three dimensional distribution of radiation dose with 1°×1°, 100m altitude intervals -Aviation Meteorological Office(AMO) of KMA will provide the information to the airline companies

KMA Space Weather Prediction Model (2/2) 5 Solar flare model produces the probability of occurrence of the flare -using McIntosh’s sunspot group classification and, -change in the area of sunspot group, which is SRS(Solar Region Summary) from NOAA Solar Flare Solar proton model uses flare generating regions -producing the probabilities of proton to affect Earth and, -producing the time of the maximum flux to affect Earth Solar Proton

 Development and research of prediction model  Improvement of cosmic radiation dose model for aviation  Development of solar proton prediction model  Analysis and application of prediction model using KSEM data  The study of space weather effects on weather and climate (air quality, meteorological elements, etc)  Space weather service  Application of space weather data, especially KSEM data  Public service of prediction model data  Sharing of space weather products of KMA using WMO’s space weather portal and DCPC  Contribution of training  Training experts for utilizing of KSEM data  Training space weather monitoring, analysis and model operators  International/Domestic cooperation  Technical improvement through various cooperations (NOAA, NASA, ESA, and academies and Institutes)  Participating in international conference or data/information exchanges (e.g. activities as a member of IPT-SWISS : WMO expert members) KMA Space Weather Policy and Future Plan 6
