Cloud, Aerosol, Radiation 
Professor Junshik Um (엄준식)
My work has been focused on atmospheric physics - the microphysical and radiative properties of atmospheric particles (i.e., cloud and aerosol particles) using in-situ aircraft measurements, satellite and surface observations, and theoretical calculations.
