25 years of observations of the ozone density vertical profiles at Osservatorio Atmosferico of CETEMPS in L'Aquila (Italy).
Rizi V., Iarlori M.
This contribution is devoted to the presentation of the multi-annual database of stratospheric ozone density vertical profiles as measured almost continuously at CETEMPS starting from 1991. The measurements were done with a DIfferential Absorption Lidar (DIAL) in the period between 1991 and 1999, and mainly with Electro Chemical Cell (ECC) ozone-sondes flying with meteorological balloons (1994--present). The contribution also includes and discusses some results concerning the trends of the ozone concentrations in troposphere and stratosphere.
