Assessment of sources of uncertainty in passive samplers of ambient air quality : evaluation Lakeland Industry and Community Association airshed 2009-2011
Passive samplers are subject to a myriad of sources of uncertainty, which affect their precision and accuracy. To investigate this uncertainty, an evaluation of passive sampler data for SO2, NO2, O3, and H2S was carried out in the Lakeland Industry & Community Association in east-central Alberta …

Proximity to Potential Sources and Mountain Cold-trapping of Semi-volatile Organic Contaminants
… of the sampled air through construction of an airshed, especially if wind is highly directional and population distribution is very non-uniform. The airshed concept was improved upon by introducing a ‘geodesic’ grid of equally spaced cells, rather than a simple latitude/longitude grid, to avoid …

Multiscale Spatial and Temporal Modelling of Fine Particulate Matter (PM2.5) from Wildfire Smoke Using Remote Sensing and Statistical Methods
… ANN for the 2014 to 2017 fire seasons and each airshed zone in Alberta. The study demonstrated how MODIS AOD could be incorporated within statistical models to provide reliable predictions of daily PM2.5 concentrations over wildfire events, to feed health and epidemiological studies. The results …
