Using satellite data map pollution concentrations for 5,600 km2 area.
Identify “hot spots” spatially at 1-km2 resolution hour by hour for the following air contaminants:
Data sourcesData sources Ground level air quality monitors
NAPS permanent stations (3) One Quebec station (PM2.5 & O3) Mobile labs for 8 locations
Aura satellite data (13 x 24 km resolution) Air and ground transportation data Meteorological data Land use data Data processing by A-MAPS Environmental
Public Health Policy ChallengesPublic Health Policy Challenges
Answers required: What sort of spatial accuracy and temporal
frequency for air pollutant concentrations is needed to comply with public health requirements?
What response or action is needed at urban “hotspots” for short duration high intensity events or for extended events?
What threshold for each pollutant should be established as a trigger for corrective action?

Sample of roads with pollution above standard
Ottawa/Gatineau exhibit similar “hot spots” during peak hours
Future AQ modelling at neighbourhood level
