Acidity, defined as pH, is a central component of aqueous chemistry. In the atmosphere, the
acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the …

This article describes the governing equations, computational algorithms, and other
components entering into the Community Multiscale Air Quality (CMAQ) modeling system …

This comprehensive text describes the atmospheric processes, numerical methods, and
computational techniques required for a scientist to successfully study air pollution and …

The development of models to assess air pollution exposures within cities for assignment to
subjects in health studies has been identified as a priority area for future research. This …

Despite more than 20 years of regulatory efforts, concern is widespread that ozone pollution
in the lower atmosphere, or troposphere, threatens the health of humans, animals, and …

We have developed a three‐dimensional Eulerian regional acid deposition model to
calculate episodic chemical concentrations and dry and wet deposition of acids in North …

The kinetic preprocessor (KPP) is a software tool that assists the computer simulation of
chemical kinetic systems. The concentrations of a chemical system evolve in time according …

Photochemical air quality models play a central role in both schentific investigation of how
pollutants evlove in the atmosphere as well as developing policies to manage air quality. In …

The numerical algorithms which we use to simulate the advection, diffusion, sedimentation,
coagulation and condensational growth of atmospheric aerosols are described. The model …

In the numerical simulation of atmospheric transport-chemistry processes, a major task is the
integration of the stiff systems of ordinary differential equations describing the chemical …
