When is air pollution at its worst in Woodstock?
In Woodstock, air quality changes through the year largely because of surrounding dairy farms and a growing auto-parts sector. Air quality is generally good, though spring and fall fieldwork stir up dust and occasional agricultural burning, and summer humidity can trap haze close to the ground. Wind can carry dust well beyond the fields themselves during the busiest planting and harvest weeks.
Are air quality levels in Woodstock 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.
