The air over Tim Hortons Field varies through the year, influenced by its location in east Hamilton, not far from the harbourfront industry. Air quality here tends to dip in summer, when heat and industrial output combine, and again briefly in winter when cold, calm air traps emissions near ground level. Wind direction off the harbour plays a large role in how far pollutants travel into surrounding neighbourhoods.

Are air quality levels in Tim Hortons Field based on measurements or forecasts?

It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
