Atmospheric Science aims to enhance the understanding of various climate phenomena and the atmospheric environment, with the ultimate aim of minimizing the damage stemming from inevitable climate disasters and anthropogenic atmospheric pollution, based on scientific research. Each sector of our society requires information relating to the atmospheric environment. In fact, with developments in engineering technology, including computers, testing equipment, and satellites, the technologies related to observation, analysis and prediction have improved rapidly, and this information on the atmospheric environment is being used to facilitate overall social and economic activities. In the Atmospheric Sciences, phenomena become visible in ways that range from being very small in scale to global in scale. In addition, as there are phenomena that have non-linear traits of different scales, the entire volume of the global atmosphere must be examined with a limited yardstick in diagnosing the atmospheric environment and predicting meteorological phenomena, which involves massive numeric calculations. Atmospheric Sciences makes use of this massiveness, and applies the latest technologies in interpreting numbers in terms of physical laws. Furthermore, as the potential impacts of climate change triggered by increased greenhouse gas emissions from human activities, as well as by damage from industrial development, have become more evident, as can be seen from acid rain, depletion of the ozone , desertification, and frequent climate abnormalities, the need to have a better understanding of Atmospheric Sciences to enable a sustainable future has become clearer and all the more essential. To this end, researchers in Korea and around the world have begun to conduct many research projects to understand and predict the changes in the atmospheric environment and the abnormal climate phenomena of the Earth’s atmosphere. These efforts are supported by a number of international agreements. Accordingly, Atmospheric Science is emerging as a promising cutting-edge field in the 21st century.
