When is air pollution at its worst in Prescott?
Prescott's air quality follows a clear seasonal pattern, as the cooler winter months typically bring the cleanest air of the year; by contrast, summer heat drives ozone formation, and blowing dust from spring winds can push particulate levels up abruptly. Monsoon storms in July and August can either clear the air with rain or stir up dust ahead of the storm front.
Are air quality levels in Prescott 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.
