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 ...

Volcanic ash dispersion modelling and detection encompasses the simulation of ash release, transport and deposition alongside the real-time observation of ash plumes. Modelling frameworks range from ...

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 ...

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 ...
