Ship-Based Incoming Solar and Longwave Radiation, 2008 ArcticNet, Northern Baffin Bay

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) -Incoming UV-A radiation (Kipp & Zonen UVS-AB-T) -Incoming UV-B radiation (Kipp & Zonen UVS-AB-T)

All instruments were mounted on a platform above the wheelhouse of the CCGS Amundsen
