Air Quality & Odour Modelling

Air Quality & Odour Dispersion Modelling

RSustain predicts the transport and concentration of air pollutants and odorous compounds using regulatory-approved dispersion models. Our modelling supports Environmental Clearance applications, industrial licence renewals, and lender due diligence — ensuring compliance with ambient air quality standards.

Tools

We use AERMOD (steady-state Gaussian plume model) for near-field regulatory applications and CALPUFF (Lagrangian puff model) for complex terrain, coastal, and long-range transport scenarios.

Applications

• Stack emission impact assessment
• Fugitive emission modelling
• Odour dispersion and receptor analysis
• Cumulative air quality impact studies
• Source apportionment for airshed management
