The air quality modeling community breathed a collective sigh of relief when a critical U.S. Environmental Protection Agency’s (EPA) modeling guidance finally became effective this year. The Guideline ...

The U.S., Environmental Protection Agency’s new modeling guidance makes a complicated situation more likely to occur at your plant. After reading a little background science, the impacts on your plant ...

Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that solve the mathematical equations ...

A new paper details the development and utility of a computer model for the dispersion of volcanic smog or 'vog,' which forms when volcanic sulfur dioxide gas interacts with water and coverts it to ...

Lagrangian particle dispersion models represent atmospheric transport by tracking individual particles or air parcels moving with the flow. This approach contrasts with Eulerian models, which solve ...

Meteorological dispersion modeling (DM) and land-use regression modeling (LUR) are alternative methods describing small scale variations in air pollution levels, and both have been documented to ...

Across the U.S., 17% of the population live near a toxic release facility, ranging from 6.5% in Hawaii to 37.3% in Wisconsin (Stacker.com). That means 56 million Americans live close to a facility ...
