Arctic UV Irradiance Observations: AON Project Findings

Explore UV irradiance observations from the Arctic as part of the AON project. Key highlights include spectral irradiance measurements since 2004, secondary data products on radiation levels, ozone, and cloud depth. Published in Atmospheric Chemistry and Physics, this data is available at CADIS and www.biospherical.com. Compare Summit data with South Pole and Barrow for a comprehensive analysis of 5.5 years of UV measurements, including cloud effects quantification.
