Monitoring Local Pollution Across Canada


Creating National Air Pollution Models for Population Exposure Assessment in Canada (7 Page pdf, Perry Hystad, Eleanor Setton, Alejandro Cervantes, Karla Poplawski, Steeve Deschenes, Michael Brauer, Aaron van Donkelaar, Lok Lamsal, Randall Martin, Michael Jerrett, and Paul Demers, Environmental Health Perspectives, volume 119, number 8, August 2011)

Today’s focus is on a study of how well the national air pollution network, supplemented by satellite data and regional land use regression modeling, can estimate local variability in 7 Canadian cities. Modelling improved the  prediction of variability of NO2 from 18% using standard interpolation to 43% with supplemental data and techniques.

NO2 model (0-105 ug/m3)                                                               0                    1,000 km (1 km resolution)
