Ground based in situ measurements of arctic cloud microphysical and optical properties at Mount Zeppelin, Svalbard
International audience Climate simulations suggest that cloud feedback plays an important role in the arctic warming. Moreover, the high seasonal variability of arctic aerosol properties is expected to significantly impact the cloud properties during the winter-summer transition. Field measurements...
