AB: Within the two-year project DANDELIONS (Dutch Aerosol and Nitrogen Dioxide Experiments for vaLIdation of OMI and SCIAMACHY), a 9-week campaign took place. The location was the Cabauw Experimental Site for Atmospheric Research (CESAR, 51N, 5E), which is often subject to considerable tropospheric pollution. The campaign focused on measurements of nitrogen dioxide, atmospheric aerosols, and ozone. Five MAXDOAS instruments and one lidar provided data on the nitrogen dioxide total and tropospheric columns, and profiles (0 - 2.5 km). These were intercompared, and also compared to OMI and SCIAMACHY overpass data. The homogeneity of the tropospheric field was studied. A range of permanent aerosol instrumentation, including sun photometers, an aethalometer, nephelometer, boundary layer lidar and radio sonde profiles and MAX DOASes, was used to provide correlative data for OMI and AATSR aerosol optical depths. Ozone Brewer, ozone sondes, and MAX DOASes provided information on tropospheric and total ozone, to be compared with OMI and SCIAMACHY results. Preliminary results show that satellite and groundbased data compare well. In our presentation, we will show information on the homogeneity of the tropospheric pollution, both in ground based and from satellite data. We will also discuss the quality of the OMI data.
