Abstract

At low tangent heights, clouds are frequently detected in the field of view and, when retrieving profiles of atmospheric composition, cloud-contaminated spectra are usually excluded.

Here we present results of an investigation into various cloud parameters which may be retrieved from such spectra: cloud top height, cloud depth, particle number density and effective radius.

Preliminary results are shown of a cloud top height retrieval from actual MIPAS spectra and compared with colocated spectra from the ACE solar-occultation instrument.
