Areas of Expertise
I have extensive research expertise on atmospheric models (Earth System Models, global climate and chemistry-transport models) and analyses of satellite, aircraft, ground-based observational data. The implementation of atmospheric chemistry and aerosol physics into global climate forecasting system of National Meteorological Research Institute for Korean Meteorological Administration and the successful development of enhanced Earth-Environment modeling capability for the Korean government NIER clearly demonstrates my dedication to global climate/environmental science and also my capacity of handling science computer codes and high-performance computers. 15 years ago, I had developed a Global Climate-Chemistry Modeling (GCCM) System for NIER/ME (Ministry of Environment) that links two well-known research models, a state-of-the-art chemistry transport model “Harvard GEOS-Chem” and a climate model “NCAR CCSM-3”. The modeling capability, GCCM, had been assessed relative to extensive measurement data and now highly applied to understand the past and future environmental changes related to climate changes in East Asia as well as all around the World.
Scientifically, I have been focused on the improvement of sub-seasonal prediction over East Asia. Long ago (2003-2010), I have conducted 3-dimensional whole atmosphere model-based calculation of global warming potentials for Halons and ozone depletion potentials for several replacement chemical compounds. Those model-based analyses of climate and ozone metrics have been published at atmospheric chemistry and physics and were reported and cited at WMO-UNEP ozone assessment in 2011.
Among my past research works was a development of advanced atmospheric modeling system of global Krypton-85 and Xenon isotopes background concentrations for improved capability of clandestine uranium separation and nuclear test discrimination. This modeling is for the concept of wide-area detection of clandestine nuclear actions. I believe this modeling capability is eventually applied and used to my country Republic of Korea when proper funding and international cooperation are reached to scientist like me.
I have used various supercomputers at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign and at National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory. During my research activities, I had solved various issues met during the use of NERSC’s and NCSA’s supercomputers by myself or sometimes actively with NCSA’s and NERSC’s consultants.
In summary, my expertise includes
Earth System Modeling and Global Chemistry Climate modeling
Numerical modeling of atmospheric chemistry, physics and dynamics: development of stratospheric dynamics model and improvements of chemistry and radiative transfer models
Long-term transport and variability of stratospheric tracers by wave activity and mass circulation including analyses of satellite data through statistical tools (EOF, LDA, SVD, etc.)
Global climate modeling and chemistry-transport modeling
Global transport modeling of radionuclides such as Krypton-85
Satellite data handling through objective and statistical analysis
Atmospheric dispersion modeling: AERMOD and CALPUFF
Computer expertise on Fortran laSynergistic Activitiesnguage, Interactive Data Language (IDL), shell programming, parallel programming and computing powers including Digital Alpha Unix, SGI IRIX Unix, Linux Alpha, and x86-64 64-bit computer clusters.
Synergistic Activities
I have conducted various researches based on my expertise in observational datasets and in numerical modeling of global atmospheric dynamics and chemistry. My specific research area include 1) Earth System Modeling: Improve sub-seasonal climate predictions by considering impacts of ozone and other climate forcers, 2) Atmospheric lifetime and ozone effects of replacement compounds including ODP and indirect GWP calculations, 2) Global climate modeling coupled with interactive chemistry-aerosol-cloud-radiation, 3) Evaluation and inter-comparison of Earth System Models with observational database such as satellite, aircraft, and sonde data, 4) the long-term variability of stratospheric tracers associated with wave activity and residual circulation, 5) The interaction of atmospheric dynamical processes with atmospheric chemistry and 6) Global transport of radionuclide.
While in the U.S., I conducted projects for companies such as Boeing, Honeywell (now Honeywell/Du Pont) and Albemarble companies. For Boeing, I and a student have developed evaluation tools to see the performance of the state-of-the-art chemistry transport models which were presented in NASA GMI meetings. For Honeywell/DuPont and Albemarble companies, I have conducted assessment studies on the effect of new chemical compounds on the environment, based on the model-based index such as Ozone Depleting Potentials (ODPs) using a global chemistry transport model called as MOZART version 3. For the U.S. EPA, I have conducted another assessment studies on the effects of greenhouse gases on the atmosphere based on the climate metric, Global Warming Potential (GWP).
From October 2010, I have been working at environmental appraisal center of Korea Environment Institute (KEI). Since my major role is the atmospheric assessment of new pollution source, I have studied AERMOD and CALPUFF modeling tools and applied those models to dispersion experiments of air pollutants resulting from building and operations of power plant and industrial complexes. I have been preparing for KEI dispersion modeling system to make AERMOD/CALPUFF correctly applied and used for environment impact assessment.
I had served as an associate editor at KASA (Korean Atmospheric Scientists in America and oversea) for a year March 2007 to March 2008. I helped publish monthly KASA newsletters to Korean community, which shares lives and researches of Korean atmospheric scientists in the U.S.
I thus have extensive experience with the most advanced modeling tools and have made companies’ needs fulfilled through my dedicated works
