Data Notes:
- There are two ambient air monitoring stations in Simcoe Muskoka, in Barrie (Simcoe County) and in Dorset (Muskoka District).
- The ambient air monitoring station in Barrie is the only one in Simcoe Muskoka that collects hourly data on all three pollutants needed to calculate the AQHI. Calculations for AQHI in Dorset are based on an estimated value of nitrogen dioxide, following direction from the Ministry of Environment, Conservation and Parks.
