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. As part of this integrated dataset, the following radiation variables were recorded at 1 minute intervals (instrument used to collect each variable is in parentheses): incoming shortwave radiation (Eppley pyranometer, model PSP); incoming longwave radiation (Eppley pyrgeometer, model PIR); incoming photosynthetically active radiation (Kipp & Zonen, PAR-Lite). All instruments were mounted on a meteorological tower on top of the wheelhouse of the research icebreaker CCGS Amundsen.

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 HMP45C212) - 15m height; relative humidity (Vaisala HMP45C212) -15m height; and, surface temperature (Apogee IR Transducer SI-111) - 8m height, atmospheric pressure.
