GLOBAL DISTRIBUTIONOF OZONE VERTICAL PROFILES FROM GOMOS MEASUREMENTS 2002-2006

GOMOS (Global Ozone Monitoring by Occultation of Stars) on board the Envisat satellite measures O3, NO2, NO3, H2O, O2, aerosols and neutral density in the stratosphere and mesosphere by detecting absorption of starlight in ultraviolet, visible and near-infrared wavelengths. During bright limb conditions GOMOS will also measure scattered solar radiation. GOMOS will deliver ozone concentration profiles at altitudes 15-100 km with a vertical sampling 0.3‐1.7 km and with global coverage. As a self-calibrating method stellar occultation measurements provide a basis for a long-term global monitoring of ozone profiles. Using GOMOS measurements we have collected zonally averaged global distribution of ozone vertical profiles between 15-100 km. The distribution is provided with 10 deg. latitude resolution at 1 km vertical grid. The time resolution is month and the time coverage is from August 2002 to the end of 2006.
