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 since 1991. The measurements were done with a DIfferential Absorption Lidar (DIAL) in the period between 1991--1999, and mainly with Electro Chemical Cell (ECC) ozone-sondes flying with meteorological balloons (1994--present). The presentation also includes and discusses some results concerning the trends of the ozone concentrations in troposphere and stratosphere.
