A paper by BSI senior scientist Dr. Germar Bernhard titled "Trends of solar ultraviolet irradiance at Barrow, Alaska, and the effect of measurement uncertainties on trend detection" has been published in Atmospheric Chemistry and Physics. The paper highlights the importance of factors other than ozone on past high-latitude UV levels. The publication is based on data of one of the UV spectroradiometers operated by BSI as part of NSF's Arctic Monitoring Network. The paper is available here.
