An intercomparison of bulk aerodynamic algorithms over sea ICE during the surface heat budget of the arctic ocean experiment

Four aerodynamic algorithms from the Community Climate System Model (CCSM), the European Center for Medium-Range Weather Forecasts (ECMWF) model, the Arctic Regional Climate System Model (ARCSyM), and the National Center for Environmental Prediction (NCEO) were compared. The data used was from the SHEBA experiment undertaken on an ice floe in the Arctic Ocean. Turbulent flux measurements were made at a 20-m high tower that was located at the ice camp and at four portable mesonet (PAM) stations. It was shown that there was a large disagreement under most conditions between what the algorithms produce using observations from the level above the first level at the 20-m tower.
