- W84781533 abstract "In order to improve knowledge on the properties, evolution and climate impact of thetropospheric aerosol in both polar regions, two aircraft experiments have beenperformed in the Arctic from Longyearbyen/Svalbard, namely ASTAR (Arctic Studyon Tropospheric Aerosol and Radiation) 2004 (in May) and ASTAR 2007 (inMarch/April), as well as one experiment in coastal Antarctica (in December/January2006/7), using either the AWI Dornier-228 or the DLR Falcon research aircraft. In thiscontribution the main focus will be on an overview of first results of the ASTAR 2007experiment, which took place in a season where the Arctic troposphere in general isexpected to be influenced by Arctic haze pollution. Observations during themeasurement period revealed rather low aerosol number concentrations and noapparent Arctic haze event with exceptionally high aerosol concentrations and reducedvisibility in the boundary layer. On the other hand, measurements of nitrogen oxides(NOy) mixing ratios showed rather high levels which are typical for the Arcticwinter/spring time. Furthermore, during many flights thin layers with aerosolconcentrations clearly higher than background were observed mainly in the lower andmiddle troposphere, clearly marked also by enhanced sulfur dioxide mixing ratios.Different composition of these layers in terms of aerosol properties and trace gases(e.g. particle absorption coefficient, non-volatile particle fraction, carbon monoxide,NOy) point to different sources of these layers. FLEXPART analyses of air masstransport show that we in general have seen rather aged air masses. We will use thecomparison to the ASTAR 2004 and the Antarctic measurements to assess thecleanliness of the Arctic troposphere in terms of particle properties." @default.
