Unique air modelling capability

Kinectrics’ Environmental Technologies provides a complete range of air quality modelling services. Kinectrics’ internationally recognized expertise has been built on more than 20 years of in-depth air quality management experience. Our modelling work covers a wide spectrum of pollution such as acid rain, SO₂, NO_x, VOCs, ozone, particulate matter, visibility, mercury and other criteria pollutants.

To meet today’s environmental challenges and provide the best solutions available, Kinectrics uses up-to-date regulatory models as well as state-of-the-science modelling systems.

Our unique professional capabilities and long-term experience ensure innovative solutions and superior service for our clients.

Regional chemistry and transport modelling

• Kinectrics’ services address the fate of air contaminants emitted by the client which are transported hundreds of km from the originating site, and/or react chemically in the air to produce secondary pollutants.

We provide answers to questions such as:

• Where do the client’s air emissions go?
• What share of a specific pollution level in receptor areas of concern is due to the client’s air emissions?
• How does the client’s share of pollution compare to other sources of contamination and the background level of the pollution?
• What is the most effective measure to enable client compliance with air quality criteria?
• Kinectrics’ air quality modelling services can be used effectively to determine potential environmental impacts for future emission projections. (e.g. Southern China’s 15-year energy planning strategy)
• Kinectrics uses the most comprehensive regional air quality modelling system available, the U.S. Environmental Protection Agency’s Models-3/CMAQ, incorporating the state-of-the-science meteorology processor MM5 and emission processor SMOKE.
• Kinectrics’ regional modelling covers acid deposition, SO₂, NO_x, VOCs, ozone, PM_2.5, PM₁₀ and visibility.
• Kinectrics has expanded the Models-3/CMAQ’s capabilities to model the emissions, concentration and wet/dry deposition of elemental/divalent/particulate mercury. (See Journal of Atmospheric Chemistry and Physics, 3, p. 535-548, 2003)
• Other available modelling software includes MC2, ADOM, RAMS, UAM.

Air emissions modelling

• The most up-to-date software, BEIS3 and MOBILE 6 based on GIS data, is used to model regional biogenic and mobile emissions.

• Kinectrics uses the modelled emissions inventory to conduct assessment studies on the relative importance of natural vs. anthropogenic emissions and NO_x vs. VOCs emissions. Our studies can evaluate the consequences of technology and fuel changes for the transportation sector.

Regulatory dispersion modelling and plume puff modelling

Kinectrics’ capabilities include:

• Dispersion modelling for various source types such as point, line, area, volume, open pit, flare.
• Dispersion modelling with U.S. EPA regulatory models ISCST3, ISC-Prime, AERMOD and AERMOD-Prime.
• Modelling air dispersion at specific shoreline settings to account for thermal internal boundary layer (TIBL) effects.
• Plume puff modelling with U.S. EPA preferred CALPUFF for downwind distances up to 150-200 km.
• Regulatory applications for:
  • Certificate of Approval (CoA)
  • Abatement or compliance assessment
• Air quality studies for industrial parks/areas (e.g. North America and Asia).
