BC CLEAR Projects 2011-2012 (funding start dates) > A Dispersion Model Analysis and Visualization Tool for Air Quality Managers

A Dispersion Model Analysis and Visualization Tool for Air Quality Managers

posted on 6:58 PM, July 6, 2016

Project Leader: Peter L. Jackson

A challenge to managing and improving air quality is to identify the pollution sources with the largest impact, and to target these for reduction. Air pollution dispersion models, such as Calpuff, are used to calculate the impact of air pollution sources (vehicles, industries, etc.) on air quality across an entire airshed. For some pollutants, such as particulate matter (PM), there may be hundreds or even thousands of sources in an airshed. The problem is that the large databases of dispersion model outputs are difficult and time-consuming for non-modellers to access and manipulate. This project will develop a web-based interactive tool for air quality managers to use, query, and visualize a spatial database of results for Prince George from the Calpuff air quality dispersion model. This will allow those involved in air quality management, and even the public, to interactively perform source reduction scenarios and visualize their potential impact. In the future, the prototype developed for Prince George could be extended to other airsheds.

About the Fraser Basin Council

The Fraser Basin Council (FBC) is a charitable non-profit organization that brings people together to advance sustainability in British Columbia.

Where We Work

We are grateful to live and work on the unceded ancestral territories of the Indigenous Nations of British Columbia.

Our Vision

Social well-being supported by a vibrant economy and sustained by a healthy environment.

Strategic Priorities

At the Fraser Basin Council, our strategic priorities are to take action on climate change, support healthy watersheds and water resources, and build sustainable and resilient communities.

With our partners, we work on a range of collaborative, multi-sector initiatives, such as those focused on flood management, community wildfire planning, air quality improvement, energy-efficient buildings, green transportation (including the uptake of electric vehicles and expansion of charging infrastructure), watershed planning and youth-driven climate action projects.
