When is air pollution at its worst in Selkirk?
Selkirk's air quality is closely linked to its legacy Gerdau steel-mill operations along the Red River. 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 Selkirk 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.
