Abstract
In this work we use Tropospheric Vertical Column Density (TVCD) of NO 2 from SCIAMACHY processed at ISAC with the Satellite DOAS Retrieval Processor (S DRP1.0) and simultaneous re trieved Aerosol Optical Properties (AOP) processed at ISAC/CGS by using Aero sol retrieval from SCIAMACHY data Processor (ASP2.2). For selected case studies in the year 2004 the AOP obser vations will be assimilated in the PROMSAR radiative transfer model to calculate an ad hoc AMF related to each of the SCIAMAC HY pixel in the area of interest to improve the accuracy of the NO 2 tropospheric column. The method is tested studying the correlation between NO 2 TVCD and aerosol where a correlation is expected.
