| Zusammenfassung |
| We compare ground-based measurements of aerosol optical depth and Ångström parameter at
six Arctic stations in the period 2001-2006 with the results from two global aerosol
dynamics and transport models, ECHAM-HAM and TM5. Satellite measurements
from MODIS and the MACC reanalysis product are used to examine the spatial
distribution and the seasonality of these parameters and to compare them with model
results. We find that both models provide a good reproduction of the Ångström
parameter but significantly underestimate the observed AOD values. We also explore the
effects of changes in emissions, model resolution and the parametrization of wet
scavenging. |
