Air Quality Modeling Program

Jump to: Related Resources Contacts Why Do We Need Models? The Division of Air Quality regularly measures the concentration of specific air pollutants at selected monitoring locations. However, the Division also needs the ability to make future projections of air pollution levels. Computer models are a relatively inexpensive and expedient means of providing this air …

Geographic Information Systems (GIS):
Air Quality Modeling Program

The Division has used Geographic Information Systems (GIS) for air quality modeling studies since 1993 by creating its own database of relevant spatial layers. This data helps in the creation of emission inventories for ozone and fine particulate modeling. This is done through the creation of demographic surrogates so that county-wide emissions can be further …

Regional Scale Air Pollution Modeling:
Air Quality Modeling Program

What Is An Air Pollution Model? A computer model simulates the meteorological conditions and chemical reactions that chemical govern air pollution formation and transport. Why Do We Need Air Pollution Models? Pollution is formed when gaseous emissions from cars, industry, and residential sources react in the air to form particulate pollution in the winter and …

Exceptional Events Program

Exceptional events are unusual or naturally occurring events that can affect air quality but are not reasonably controllable using techniques tribal, state or local air agencies may implement in order to attain and maintain the National Ambient Air Quality Standards. Exceptional events are events for which the normal planning and regulatory process established by the …

Fireworks:
Exceptional Events Program

The Division on Air Quality would like to help Utah residents celebrate safely by reminding everyone of the potential for high concentrations of smoke associated with fireworks displays.  This smoke is largely particulate matter (PM). In prior years, DAQ has monitored extremely high concentrations of both PM10 and PM2.5 (the fine and the very fine …
