Reno's air quality reflects the Truckee Meadows valley's partial topographic enclosure between the Sierra Nevada to the west and the Virginia Range to the east, with vehicle emissions from I-80 and wood burning contributing the primary local sources. Winter inversions can trap emissions in the valley, while summer wildfire smoke from the Sierra Nevada and Great Basin ranges is an increasingly frequent severe seasonal concern.

When is air pollution at its worst in Reno?
Reno sees air quality change through the year, as the cooler winter months typically bring the cleanest air of the year; by contrast, spring winds can kick up sudden dust storms that spike particulate levels sharply for a day or two. 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 Reno 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.
