The Tropospheric Ozone Lidar Network (TOLNet) was established in 2012 to provide high spatio-temporal profiles of tropospheric ozone. These profiles allow for a better understanding of the physical processes driving the ozone budget in various meteorological and environmental conditions and to validate the tropospheric ozone measurements of spaceborne missions.
