One Hour Ozone Averages

Save the Air in Nevada County’s mission is to collect reliable data about ozone, educate the public, advocate for air pollution control measures, and protect our children from respiratory illness. To track current ozone levels in the Grass Valley/Nevada City area, each summer we operate our own monitors in each of those cities and graph data from air quality agencies.
