MAXDOAS measurements: MAXDOAS @ ground and miniDOAS @200m height DSCD comparison: highlight of a NO2 layer over or under 200m VCD comparison: consistency with in-situ data (ground & 200m) RTM and errors related to geometrical approximation for VCD (several geometries, NO2, aerosols loads) Satellite validation: OMI and SCIAMACHY cloud issues for several retrieval schemes Poster summary
