Atmospheric Emissions Management

Turning data into knowledge

Zephyr has three decades of experience in helping clients to characterise, manage and control conventional air pollutants across all industry sectors.

​

We offer a holistic approach to air quality management, however our key services can be summarised as:

• Air quality / odour impact assessment

• Atmospheric dispersion modelling

• Emission inventory development

• Ambient air quality monitoring network design

​

We use the optimal air quality modelling tools to fit your application. For straightforward evaluations, we may use screening level tools such as CALINE, CAL3QHCR or the TRAQ roadway assessment tools.

More typically, we apply regulatory dispersion models such as the USEPA's AERMOD or the CALPUFF or TAPM modelling suites.

For advanced, or regional assessments we apply state-of-the-science software including WRF, WRF-CHEM, SCIPUFF or CMAQ.

Having previously maintained NATA-accredited methods for ambient air quality monitoring, we are skilled in designing an air quality monitoring solution that balances budget and utility.
