The Atmospheric Sciences staff at Exponent provides consulting services in air quality and atmospheric sciences. Our staff specializes in air quality and meteorological modeling, permitting, and licensing. We investigate accidental releases of chemicals to the atmosphere, simulate transport and fate of chemical substances, and develop measures of prevention and control, such as emergency preparedness and response. Areas of air quality modeling include: industrial plumes, dense gases, photochemical reactions, mobile sources, forest fires, explosions, radioactive releases, and odors. Our atmospheric scientists work closely with chemical engineers, combustion specialists, atmospheric modelers, and thermal and process engineers to predict and evaluate the dispersion of air emissions. We also work with Exponent’s risk assessors to evaluate health risks posed by atmospheric releases to the ambient air and to indoor environments, as well as the health effects of air pollution.
