November 2022

There's a new tool to assist with dispersion modelling.

The CALNO2 post-processor can be used to process one or more CALPUFF concentration files.

It also calculates nitrogen dioxide (NO2) concentrations from modelled nitrogen oxides (NOx) using either:

  • Ambient Ratio Method (ARM) or,
  • Ozone Limiting Method (OLM)

The application of both methods is consistent with the nitrogen dioxide modelling guidance.

Visit the CALPUFF Modelling System to download this tool and its user guide.

The Ministry of Environment and Climate Change Strategy, Metro Vancouver Reginal District, Fraser Valley Regional District and Environment and Climate Change Canada have developed the Lower Fraser Valley Photochemical Modelling Guideline.

This guideline provides recommendations on photochemical modelling techniques for estimating impacts of air emissions from large projects on secondary pollutants (for example, ground-level ozone and secondary particulate matter).

This guideline is primarily intended for use in the Lower Fraser Valley.

Please visit air quality modelling to access this guidance document.

  • Fine particulates (PM2.5)
  • Ground-level ozone
  • Nitrogen dioxide (NO2)
  • Sulphur dioxide (SO2) and the associated management levels
