  <dc:description xmlns:ns0="xml" ns0:lang="en">The high-Alpine ice-core drilling site Colle Gnifetti (CG), Monte Rosa, Swiss/Italian  Alps, provides climate records over the last millennium and beyond. However, the full  exploitation of the oldest part of the existing ice cores requires complementary  knowledge of the intricate glacio-meteorological settings, including glacier dynamics.  Here, we present new ice-flow modeling studies of CG, focused on characterizing the  flow at two neighboring drill sites in the eastern part of the glacier. The3-D full Stokes  ice-flow model is thermo-mechanically coupled and includes firn rheology, firn  densification and enthalpy transport, and is implemented using the finite element  software Elmer/Ice. Measurements of surface velocities, accumulation, borehole  inclination, density and englacial temperatures are used to validate the model output.  We calculate backward trajectories and map the catchment areas. This constrains, for  the first time at this site, the so-called upstream effects for the stable water isotope  time series of the two ice cores drilled in 2005 and 2013. The model also provides a 3- D age field of the glacier and independent ice-core chronologies for five ice-core sites.  Model results are a valuable addition to the existing glaciological and ice-core  datasets. This especially concerns the quantitative estimate of upstream conditions  affecting the interpretation of the deep ice-core layers.</dc:description>
