Experts in Air Modeling & Exposure Assessment
Trusted by Communities, Lawyers & Regulators
Led by science, the RoseyField's Team specialize in air modeling, risk assessment, asbestos exposure assessment, historic dose reconstruction, environmental chemistry, water system modeling, and chemical fate and transport.
RoseyField’s
Air Modeling
Dr. Paul Rosenfeld and his team brings decades of specialized expertise in environmental science to support communities, attorneys, and regulatory bodies with evidence-based assessments across multiple domains. In the field of air modeling and risk assessment, Dr. Rosenfeld applies U.S. EPA-approved dispersion models such as AERMOD to estimate the spread and concentration of airborne contaminants. His modeling work helps quantify exposure and health risks from diesel exhaust, refinery fires, chemical releases, and PFOA emissions—critical in litigation and regulatory decision-making. Roseyfields also runs ALOHA, AERSCREEN and other air modeling software programs when appropriate.
