Atmospheric science is the study of the physics, chemistry, and dynamics of the atmosphere and its interrelationship with the hydrosphere and the biosphere. Students gain advanced knowledge of air quality, meteorology, atmospheric chemistry, micrometeorology, biometeorology, climate dynamics, mesoscale meteorology, large-scale dynamics, and numerical weather prediction. Students graduate with the qualitative and quantitative skills necessary for professional research and teaching in the chemistry and dynamics of the atmosphere and its interrelationship with the hydrosphere and the biosphere. The Graduate Group in Atmospheric Science offers both M.S. and Ph.D. degree programs. A student may place emphasis on graduate work in one or more of the following fields: air quality meteorology, atmospheric chemistry, cloud physical processes, biometeorology, micrometeorology, numerical weather prediction, remote sensing, climate dynamics, large-scale dynamics, meso-scale and boundary-layer meteorology, computational geosciences, extreme weather, and climate change impacts. The diverse and extensive backgrounds of the faculty allow opportunities for interdisciplinary training and research.
Students in the atmospheric chemistry and air quality program at Davis study a wide range of questions regarding the emission, transformation, transport and deposition of air pollutants. Research projects include measurement and modeling of emission, deposition and dispersion on scales ranging from the microscale processes around individual plants to mesoscale flows over an entire state. The study of air quality problems is multi-disciplinary as is reflected by the diversity of training and departmental affiliation of the Graduate Group members associated with this specialty.
