Wind direction across the river determines how much of the industrial output drifts into town on any given day.
Are air quality levels in Jonquiere (secteur) 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.
