Today we review a paper presented at the biannual Upwind-Downwind Conference in Hamilton that describes the development of a fairly unique urban air quality program. The program was given a boost in 2007 by a project that combined satellite air quality data from space with observations from a dozen ground stations to produce maps at 10 km resolution at 10 minute intervals for a year over the national capital area (which includes the twin cities of Ottawa and Gatineau). Further applications of these data with real-time traffic flow data allowed for mapping down to the street level in downtown Ottawa and assessments of health impacts near these roads which showed that over 50% of schools and old age homes are located within 50 m of heavy traffic, placing the most vulnerable residents at risk from vehicle emissions. A new program has just been announced by the University of Toronto to examine similar applications of roadside emissions and health impacts in Canada’s largest city. Key Quotes: Satellite AQ Pilot Project (2007-2008)
- “Map pollution concentration spatially hour by hour to identify patterns (“hot spots”)
- One full year of monitoring (Jul’07-Jun’08) six major pollutants:Nitrogen oxides (NO, NO2, NOx), Ground Level ozone, Carbon Monoxide, Particulate Matter 2.5
- Three months of integrating satellite data and ground monitoring stations”
- Translate Air Quality maps from the pilot project (2008) into meaningful health impacts (morbidity, mortality and $$$)
- Use Air Quality Benefits Assessment Tool (AQBAT)
- Obtain a tool for health impact assessments of changing traffic flows”
