Airborne imaging DOAS during AROMAT — •Andreas C. Meier1, Anja Schönhardt1, André Seyler1, Andreas Richter1, Thomas Ruthz2, and John P. Burrows11Uni Bremen, Institute of Environmental Physics — 2FU Berlin, Institute for Space Sciences

The AROMAT campaign (Airborne Romanian Measurements of Aerosols and Trace Gases) was carried out in September 2014 as part of the preparations for the space-borne Sentinel-5 Precursor air-quality monitoring mission.

The IUP-Bremen contributed to this campaign with its imaging DOAS instrument, AirMAP. This instruments allows the detection of column densities of trace gases under the aircraft at a high spatial resolution (30 × 80 m2). Mapping patterns were flown over Bucharest, that provided coverage the whole city in approx. 2.5h. These measurements show the spatial distribution of NO2 column densities below the aircraft and show huge amounts of NO2 inside the city centre and a strong gradient towards more rural areas.
