air dispersion modelling software free download

Support Center for Regulatory Atmospheric Modeling (SCRAM).

Develop local and regional-scale air quality and related climate data.

Assess risks posed by criteria and hazardous air pollutants (HAPs).

Inform air quality permitting decisions.

Support the development of major energy and transportation sector rules.

Characterize the role of background air pollution on NAAQS attainment and implementation.

This research is also enhancing the ability to conduct multipollutant air quality assessments at local, regional, national, and global scales in addition to developing multimedia and multi-stressor models to address complex environmental issues. They are critical for determining the relative contributions from different sources, monitoring compliance of air quality regulations, and making policy decisions. EPA has an extensive air quality modeling program that develops, evaluates, and applies models to support a wide variety of air quality management needs.Īdvances in modeling enables users to better estimate the relationship between sources of pollution and their effects on ambient air quality , predict the impacts from potential emission sources, and simulate ambient pollution concentrations under different policy scenarios.

This system is Linux based.Researcher studies results from EPA’s Community Multiscale Air Quality Model (CMAQ).Ītmospheric modeling is used by air quality managers to make decisions on effective and efficient ways to implement the National Ambient Air Quality Standards (NAAQS) and improve air quality.
