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 ...

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 ...

ABSTRACT Ensemble simulations made using a coupled atmospheric dynamic model and a probabilistic Lagrangian puff dispersion model were employed in a forensic analysis of the transport and dispersion ...

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 ...

Prominent Bismarck-area developer Chad Wachter was invited to two meetings with Summit Carbon Solutions executives and others earlier this year and was given access to a carbon dioxide dispersion ...

During unplanned chemical releases, there are bound to be more questions than answers. Plume models are the best way to answer these questions and more. A plant-wide power outage at Pasadena Refining ...

A new class of geometric dispersion models associated with geometric sums is introduced by combining a geometric tilting operation with geometric compounding, in much the same way that exponential ...
