A. Kokhanovsky W. von Hoyningen-Huene V. V. Rozanov S. Noël K. Gerilowski H. Bovensmann K. Bramstedt M. Buchwitz J. P. Burrows Institute of Remote Sensing, University of Bremen, Germany The Semianalytical CloUd Retrieval Algorithm (SACURA) is applied to the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) data. In particular, for the first time we derive simultaneously cloud optical thickness (COT), liquid water path (LWP), cloud top height (CTH), and cloud droplet radius (CDR) using SCIAMACHY measurements in the visible (442 nm, COT), in the oxygen A-band (755–775 nm, CTH) and in the infrared (1550 nm, CDR). Some of the results obtained are compared with those derived from the Medium Resolution Imaging Spectrometer (MERIS), which has better spatial resolution and observe almost the same scene as SCIAMACHY.
