Information on Ontario's Air Quality from the Ontario Ministry of Environment and Climate Change.
Clean Air Hamilton is a multi-stakeholder group dedicated to improving air quality in Hamilton's community.
Denis Corr has conducted mobile air pollution monitoring since 2005 in Hamilton. These campaigns traversed the city collecting mobile air pollution data for PM10, PM2.5, NO, NO, NO2, NOX, O3 and SO2. The air pollution data are finely resolved, and averaged over 1 minute intervals. Campaigns were conducted to collect data in areas with diverse land uses and during different meteorological conditions. These data are the foundation of this work.
In our work, we required building a model that could utilize information from both the stationary and mobile air pollution monitoring data. The stationary monitoring data is updated in real-time (hourly), but does not have the spatial coverage across Hamilton; while the mobile data has a great spatial coverage, is only historical information. Our goal was to link these data to gain the most information possible from the monitoring network. Air pollution data collected with mobile monitoring were standardized to five air pollution monitors that are operated by the Ontario Ministry of the Environment, which included Hamilton Downtown, Hamilton Mountain, Hamilton West, Burlington and Chatham. This provided ratios of the mobile concentration monitored locally to the stationary air pollution monitoring data at the time of collection. These ratios were separated into groups based on the wind regime that occurred during collection. Within each zone the standardized values were averaged and assigned to the zone for each wind regime. The values assigned to each zone can be multiplied by the current stationary monitoring values to model the air pollution for each zone. The current system models SO2, NO, NO2, NOX, PM2.5, Increased Percent Mortality Risk, and the AQHI.
The model is updated every hour with the most recent values from the fixed location air pollution and meteorological stations. Using the updated information we then update the maps. Currently this process occurs about 30 minutes past the hour.
We are happy to discuss this project with anyone who is interested. As well, we are open to collaborative research dealing with Air Pollution.
