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 ...

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 ...

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 ...

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 ...

How sensor-driven plume dispersion modeling saves lives. 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).

Blackline Safety partnered with Vlahi Systems to integrate gas sensor data from its cloud-connected area gas detectors with the live weather data flowing into Vlahi’s CERES plume modeling software.
