Ozone and aerosol measurements with an airborne lidar system
Ozone (O3) is an important component of atmospheric pollution. It indirectly controls the chemistry of the troposphere (atmospheric region typically below about 10 km in altitude) and directly contributes to the greenhouse effect by being a radiatively active gas. In the lower stratosphere (atmospheric region typically between 10-30 km in altitude), O3 is the principal absorber of solar ultraviolet radiation, and because of this, it protects life at the surface from harmful ultraviolet radiation. In addition, it controls the temperature in the lower stratosphere and is important in determining the chemistry of this region.
