Why do we need remote sensing to measure ozone ?
Ozone is a gas present in 2 layers of the atmposphere. Tropospheric ozone is located between the ground and 10-18 km up. The stratospheric ozone layer is generally located from 10-18 km to 50 km up.
So it is easy to understand that, except from ground level ozone, no ozone measurements can be made without remote sensing instruments such as Lidar and satellite or airborne sensors.
