Ground-based stratospheric lidar measurements for the National Ozone Expedition II
Recent measurements indicate that the column content of ozone in the antarctic stratosphere has been decreasing over the past dozen years and that major reductions occur between August and November, the late austral summer and early austral spring. Atmospheric scientists have proposed a number of theories to explain this phenomenon; however, they cannot validate these hypotheses with existing data. As part of National Ozone Expedition II, the authors will investigate the temporal variability of stratospheric aerosols and cloud distribution by using a ground-based lidar (laser infrared radar). The ground-based lidar can be used to monitor continuously the time and height variability of aerosols and the polar stratospheric cloud layers that occur at altitudes of greatest ozone depletion. These measurements can be correlated with other atmospheric composition measurements to infer the role of aerosol and clouds on observed ozone behavior.
