The retrieval combines spectral information in the Chappuisand Hartley absorption bands of ozone and employs the SCIATRAN radiative transfermodel. The retrieved ozone profiles are applied into two aspects.First, the sensitivity of the ozone profile retrieval to tropospheric clouds is examinedusing the SCIATRAN radiative transfer model. The considered clouds are verticallyand horizontally homogeneous. An aerosol-free atmosphere and Mie phase functionsfor cloud particles are assumed. Neglecting clouds in the retrieval, the relative errorsof ozone profile retrievals in a cloudy atmosphere are computed.
