When is air pollution at its worst in TD Station?
TD Station's air quality shifts with the calendar, largely because of its uptown Saint John setting. Summer heat can worsen conditions when plant emissions combine with sunlight to form ground-level ozone, while winter inversions occasionally trap industrial pollutants close to the ground on still, cold days. Wind direction along the river has a strong influence on which neighbourhoods feel the effects most on any given day.
Are air quality levels in TD Station 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.
