Dr. Escoffier-Czaja is a project scientist in TRC's Atmospheric Studies Group with expertise in meteorological modeling, air quality modeling and oceanography. She has conducted numerous air quality impact studies using the CALMET/CALPUFF modeling system both in United States and in foreign countries, including South Africa, Spain, China, Saudi Arabia, Iceland and Thailand. This work included both near-field modeling and long-range transport modeling for visibility impact assessments in Class I areas. Dr. Escoffier-Czaja has worked extensively on meteorological analysis and data processing as well as source emissions data analysis. She has worked on the development of new methods for visibility impact in Class I areas including the Ammonia Limiting Method (ALM), and has developed new module in CALPOST and POSTUTIL system (CALPUFF/CALMET postprocessing). She has conducted several BART analyses using the CALPUFF model for industrial clients throughout the country. Dr. Escoffier-Czaja has been an instructor at several CALPUFF modeling training courses. In previous research, she has worked on water vapor measured by satellite to assess the current uncertainty of the data set. In addition, she has expertise in ocean circulation, air-sea interaction, marine chemistry and corrosion.
