Abstract

Authors: Didier FUSSEN and the GOMOS team

Abstract: The ENVISAT satellite has been launched by ESA on March 1st 2002. On board, GOMOS measures the slant path atmospheric transmittance at tangent altitudes between 120 km and the ground. Apart from the major target species, the GOMOS transmittances contain small spectral details that could be exploited by averaging a large number of occultations in time-latitude bins. In particular, we will present results about the mesospheric sodium layer and the identification of polar stratospheric clouds. Also, the discovery of an OClO layer in the upper stratosphere in non-vortex conditions will be discussed. The evolution of the OClO polar activation over the period 2002-2005 will be analyzed.
