Dr. Escoffier has over 13 years of experience in the fields of meteorological and air quality studies using atmospheric dispersion models such as CALPUFF, AERMOD, and BLP. Dr. Escoffier has managed and conducted projects for long-range air quality impact studies for Best Available Retrofit Technology (BART) assessments and for Prevention of Significant Deterioration (PSD) compliance in the United States. She has also conducted near-field applications in simple and complex meteorological situations to assess compliance with air quality standards inside and outside the U.S. for aluminum industries and electric utilities. She has expertise in software development and data analysis. She has conducted research and development for a new method within the CALMET/CALPUFF modeling system, the Ammonia Limiting Method (ALM), a tool for refining nitrate particulates simulations. This technique has been used to refine long-range visibility impact assessments in U.S. national parks and wilderness areas.
Dr. Escoffier recently managed a review of the issues associated with atmospheric dispersion modeling in varying meteorological conditions funded by the UK Air Dispersion Modeling Liaison Committee. She has taught more than 20 basic and advanced CALPUFF modeling training courses provided to governmental agencies, academic, industrial, and commercial modelers in the United States, Canada, Europe, Thailand, and South Africa.
