    Abstract
    We compare daily data from the National Center for Atmospheric Research and National Centers for Environmental Prediction “Reanalysis 1” project with observational data obtained from the North Pole drifting stations in order to validate the atmospheric forcing data used in coupled ice-ocean models. This analysis is conducted to assess the role of errors associated with model forcing before performing model verifications against observed ocean variables. Our analysis shows an excellent agreement between observed and reanalysis sea level pressures and a relatively good correlation between observed and reanalysis surface winds. The observed temperature is in good agreement with reanalysis data only in winter. Specific air humidity and cloudiness are not reproduced well by reanalysis and are not recommended for model forcing. An example sensitivity study demonstrates that the equilibrium ice thickness obtained using NP forcing is two times thicker than using reanalysis forcing.

      Arctic decadal variability from an idealized atmosphere-ice-ocean model: 1. Model description, calibration, and validation 

      Dukhovskoy, Dmitry S.; Johnson, Mark A.; Proshutinsky, Andrey (American Geophysical Union, 2006-06-20)
      This paper describes a simple “multibox” model of the Arctic atmosphere-ice-ocean system. The model consists of two major modules (an Arctic module and a Greenland Sea module) and several sub-modules. The Arctic module ...

      Winter mixed-layer development in the central Irminger Sea : the effect of strong, intermittent wind events 

      Våge, Kjetil (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2006-09)
      The impact of the Greenland tip jet on the wintertime mixed-layer of the southwest Irminger Sea is investigated using in-situ moored profiler data and a variety of atmospheric data sets. The mixed-layer was observed to ...
