Air Quality in Ontario, 2014

Notes:

• The most recent available data (2014) were mapped by cut-points (based on standard deviations from the mean) across public health units (PHU) in Ontario.
• The maps show the mean distribution of air quality and pollutants in Ontario by PHU for seasonal and annual time frames. These maps were generated on ArcGIS Pro using  the Empirical Bayesian Kriging (EBK) Regression Prediction tool to generate a spatial prediction surface of air pollution distribution across Ontario.
•  We do not have sufficient data to confidently predict the mean distribution of air pollution outside the buffer zones, such as in Northern Ontario because there are no air monitoring stations in the region. Those areas were marked in grey in the maps.
