Visualizing environmental data at the EPA

Several environmental visualization projects being pursued by the US Environmental Protection Agency are discussed. One group develops models for the transport and deposition of airborne pollutants. Another group evaluates the positions of air quality monitoring sites with respect to the distribution of pollutants. Other researchers collaborate with investigators at NASA Langley and Lawrence Livermore National Labs. to examine global climate change. Still others study water quality and sedimentation in the Great Lakes region, electrical properties of carcinogens, subsurface contamination of waste disposal sites, and the air flow through and around buildings. The visualization requirements, software configurations, and general strategies for the projects are described.<>
