Reconciling aerosol light extinction measurements from spaceborne lidar observations and in situ measurements in the Arctic
Tesche, Matthias; Zieger, P.; Rastak, N.; Charlson, R. J.; Glantz, P.; Tunved, P.; Hansson, H. C. (2014-08-08)In this study we investigate to what degree it is possible to reconcile continuously recorded particle light extinction coefficients derived from dry in situ measurements at Zeppelin station (78.92° N, 11.85° E; 475 m above ... -
Seasonal variation of aerosol water uptake and its impact on the direct radiative effect at Ny-Ålesund, Svalbard
Rastak, N.; Silvergren, S.; Zieger, P.; Wideqvist, U.; Ström, J.; Svenningsson, B.; Maturilli, M.; Tesche, Matthias; Ekman, A. M L; Tunved, P.; Riipinen, I. (2014-07-21)In this study we investigated the impact of water uptake by aerosol particles in ambient atmosphere on their optical properties and their direct radiative effect (ADRE, W m-2) in the Arctic at Ny-Ålesund, Svalbard, during ...
