Abstract
Measurements of ozone in the troposphere have become increasingly important during thepast decade with reports of ozone increases on global scales that not only threaten the vitalityof the plant and the animal kingdom, but can also, since ozone is a greenhouse gas, contributeto global warming. The lidar application that is described here is specifically designed toaccommodate the needs of the scientific community to accurately measure tropospheric ozoneover a period of many years as one indicator of global change, and is intended as a prototypefor a network of tropospheric ozone lidars.
