Atmospheric Dispersion Modeling and Monitoring Zephyr’s meteorologists are recognized experts in atmospheric dispersion modeling and air quality monitoring data evaluations and are skilled in helping clients understand the process of modeling and the interpretation of modeling results. We have developed, tested, and gained regulatory agency approval for model algorithms, published articles on atmospheric dispersion modeling techniques and applications, presented papers on dispersion modeling topics at technical conferences, taught college-level dispersion modeling courses, and presented expert testimony on modeling issues. Using EPA Guideline models such as CALPUFF and AERMOD, as well as specialized use models like VISCREEN, SLAB and ALOHA/CAMEO, Zephyr’s modeling professionals provide a variety of modeling services.
