Satellite measurements of stellar scintillation in limb-viewing geometry provide unique information about small-vertical-scale gravity waves (GW) in the stratosphere and their breaking into turbulence. In our presentation, we show the results of analyses of scintillation measurements carried out by GOMOS (Global Ozone Monitoring by Occultation of Stars) fast photometers on board the Envisat satellite in 2002-2012. GOMOS scintillation measurements allow retrievals of inner of outer scales of gravity waves, GW structure characteristic and potential energy per unit mass, as well as reconstruction of turbulence structure characteristic C _{T} (2) in the stratosphere. GW and turbulence spectra parameters are retrieved by fitting modeled scintillation spectra to measured spectra. In our presentation, we explain the data analysis and show spatio-temporal distributions of gravity wave and turbulence spectra parameters in the stratosphere.
