We are the UNIST Climate Environment Modeling Laboratory (UCEM), one of dedicated labs at UNIST for climate and environmental studies since 2010. Our research area covers widely classical and recent topics in weather and climate, with a primary emphasis on climate sciences and modeling. We have been developing earth system models with a fully-interactive global carbon cycle, which is being prepared for a national use in responding to the next IPCC climate change scenario projections. We're also developing high-resolution global climate prediction models with improved water cycle, which are known to be better for simulating high-impact weather and climate anomalies. Our lab is also dedicated to understanding and improving the simulations of pronounced weather and climate variability and their changes. These include the various phenomena from the time scale of the daily cycle of warm-season precipitation, to the time scale of tropical waves and cyclones, the Madden-Julian oscillation, and to the interannual and decadal time scales of the El Nino and Southern Oscillation, and beyond. We have been supported and partnered by major research institutes and foundations, including the Korean Meteorological Administration (KMA), National Institute of Meteorological Research (NIMR), APEC Climate Center (APCC), Korea Institute of Atmospheric Prediction Systems (KIAPS), and the National Research Foundation of Korea (NRF). We are also collaborating actively with NASA Goddard Space Flight Center for joint research project and scholar exchanges.
