DIAL vertical profiles of stratospheric Ozone in Antarctica by Service d'Aeronomie/CNRS from 1991 to 1996 at Dumont d'Urville Base

The DIAL System placed at Dumont d'Urville is a scientific cooperation between Service d'Aeronomie of CNRS (France) and IROE of CNR (Italy). The system works since 1991 and produces vertical profiles of many atmospheric components. Using the differential absorption technique it produces vertical profiles of Ozone in the Stratosphere. Rawin- and ozone-sonde are by Dumont d'Urville Antarctic Station (France). All the profiles are normalized to the same altitudes.
