During the ArcticNet annual cruises of the research icebreaker CCGS Amundsen, characteristics of the near-surface atmosphere (basic meteorological elements, incident radiation) are monitored. Central to this integrated dataset, the following meteorological variables were recorded at 1 minute intervals (instrument used to collect each variable is in parentheses, and approximate instrument height above surface is indicated): wind speed (RM Young Wind Monitor 05106-10) - 16m height; wind direction (RM Young Wind Monitor 05106-10) -16m height; air temperature (Vaisala HMP45C) - 15m height; relative humidity (Vaisala HMP45C) -15m height; and, surface temperature (Apogee IR Transducer SI-111) - 8m height, atmospheric pressure.
All instruments were mounted on a meteorological tower on the bow of the research icebreaker CCGS Amundsen, except for the IR transducer SI-111, which was mounted on top of the gunwale at the ship's bow, overlooking the water surface.
