Abstract
In this work we use Tropospheric Vertical Column Density (TVCD) of NO2 from SCIAMACHY processed at ISAC with the Satellite DOAS Retrieval Processor (SDRP1.0) and simultaneous retrieved Aerosol Optical Properties (AOP) processed at ISAC/CGS by using Aerosol retrieval from SCIAMACHY data Processor (ASP2.2). For selected case studies in the year 2004 the AOP observations will be assimilated in the PROMSAR radiative transfer model to calculate an ad hoc AMF related to each of the SCIAMACHY pixel in the area of interest to improve the accuracy of the NO2 tropospheric column. The method is tested studying the correlation between NO2 TVCD and aerosol where a correlation is expected.
