<abstract>
<p>This study explores the indirect effects of anthropogenic and biomass
burning aerosols on Arctic clouds by co-locating a combination of
MODIS and POLDER cloud products with output from the FLEXPART tracer
transport model. During the activities of the International Polar
Year for the Spring and Summer of 2008, we find a high sensitivity
of Arctic cloud radiative properties to both anthropogenic and biomass
burning pollution plumes, particularly at air temperatures near freezing or
potential temperatures near 286 K. However, the sensitivity is much lower at both
colder and warmer temperatures, likely due increases in the wet scavenging of cloud condensation
nuclei: the pollution plumes remain but the component that influences
clouds has been removed along transport pathways. The analysis shows that, independent of temperature,
cloud optical depth is approximately four times more sensitive to changes in pollution levels than is cloud
effective radius. This suggests that some form of feedback mechanism amplifies the radiative
response of Arctic clouds to pollution through changes in cloud liquid water path.</p>
