During the ArcticNet annual cruises of the research icebreaker CCGS Amundsen, characteristics of the near-surface atmosphere (basic meteorological elements, incident radiation, CO2 concentration) are monitored in conjunction with surface sea water properties (temperature, salinity, dissolved CO2 and O2) to observe the relationship between the surface micro-climate and the air-sea exchange, with particular interest in CO2. 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 05103) - 16m height

-Wind direction (RM Young Wind Monitor 05103) -16m height

-Air Temperature (Vaisala HMP45C212) - 15m height

-Relative Humidity (Vaisala HMP45C212) -15m height

-Surface temperature (Everest IR Transducer, 4000.44ZL) - 8m height

All instruments were mounted on a meteorological tower on the bow of the research icebreaker CCGS Amundsen.
