Springtime Arctic aerosol: Smoke versus haze, a case study for March 2008 s h en lof Tele Bürg rook Accepted 16 June 2011 ete et al., 2004; Treffeisen et al., 2005). While in earlier studies on Arctic Haze (Rahn,1981; Barrie, 1986; Yamanouchi et al., 2005; Law and Stohl, 2007) an anthropogenic origin was already shown, several publications during recent years also revealed that biomass burning (as well forest fire as from The economical growth of East Asia may lead to increased pollution entry from this region (Koch and Hansen, 2005) but due to the temperature gradient to the Arctic this transport pattern will predominantly take place in the high troposphere. There are indications that in Siberia the boreal vegetation is spreading North (Soja et al., 2007) and forest fires might have increased during the 20th century (Kasischke et al., 2004). Furthermore the climate predictions (as unsure as they are in the Arctic) indicate an increase of Siberian fire events for the 21st * Corresponding author.

In the Arctic troposphere increased aerosol loads can occur during spring, a phenomenon which is called Arctic Haze (Quinn et al., 2007). The radiation impact of this aerosol is still poorly understood. Moreover, the Arctic environment is very vulnerable during that season, as aerosol deposition on snow or ice covered surfaces reduces the albedo and favors an earlier onset of the melting season (Flanner et al., 2007; Clarke and Noone, 2007; Stroeve et al., 2007). The direct forcing of aerosol depends, among other factors, on its soot content (Stone et al., 2008; Ramanathan and Carmichael, 2008) and surface albedo. For these reasons a modeling of the radiative impact of aerosol is still chal- lenging and large regional deviations in temperature response, including both warming and cooling, must be considered (Rinke 2007). However, so
