Ozone is monitored at a number of locations around the Lake Tahoe Basin
through the years by a variety of partners. Data is collected, analysed, and reported by the respective agency.
This report summarizes recent data collected at the TRPA sites; compares it to measurements from other concurrently operating monitoring stations and historical data collected in the Tahoe basin, and presents analyses of the temporal patterns and other indicators of emissions sources and meteorological influences that drive the pollutant concentrations.
