Junshik Um is an asistant professor in Pusan National University who has presented on “Microphysical characteristics of frozen droplet aggregates from deep convective clouds.” The main objectives of the presentation was determination of the morphological properties of single frozen droplets and frozen droplet aggregates and their radiative impacts. A cloud particle imager (CPI) mounted on the GV aircraft recorded images of ice crystals at different altitude and temperatures and CPI crystal images were analysed to identify single frozen droplets and frozen droplet aggregates (FDAs). A new algorithm developed to automatically identify the number, size, and relative position of element frozen droplets were discussed. Based on the study the number, size, and relative position of the element frozen droplets were generated and characterized by two different shape parameters, aggregation index, and the fractal dimension. Finally, the presentation forwarded that the approach is important to improve the calculations of the microphysical properties of ice crystals in upper anvil clouds.
