Long Range Transport

Modelling of air pollution at a continental and/or global scale is commonly used to evaluate impacts associated with pollutant emissions from distant sources. This can be important, for instance, when considering the relative contribution of transboundary air pollution on local air quality for policy making and regional planning. A better understanding of background pollutant levels due to long-range transport can also be important when looking at relative source contribution to new facilities, roadways, and other projects, as well as cumulative effects assessment and policy development.

Novus uses photochemical models such as CMAQ, CAMx, WRF-CHEM, Canadian GEM-MACH and GEOS-CHEM, for evaluation of impacts associated with pollutant emissions.
