Abstract

As a consequence of research efforts performed to observed any anthropogenic influence on atmospheric ozone, new systems have been developped to monitor the ozone profile and total content from the ground. As part of it an ultra-violet lidar system was implemented in 1980 at the Observatoire de Haute Provence (OHP), and was involved in different international comparison campaigns. Some results of these campaigns will be presented, with other specific comparisons as they have allowed to validate the lidar measurements performed at the OHP throughout the altitude range from the ground up to 45-50 km. Such high altitudes have been reached by means of a new generation of laser systems, the implication of which on the ozone survey in the upper stratosphere will be emphasized. Lidar systems are also potential instruments for ozone survey in the troposphere and especially their ability to perform high spatial and temporal resolution measurements, below 15 km, allows to describe some aspects of stratosphere-troposphere exchanges as will be presented.
