Abstract

Abstract This study analyzes changes in solar ultraviolet (UV) irradiances at 305 and 325 nm at selected sites located at high latitudes of both hemispheres. Site selection was restricted to the availability of the most complete UV spectroradiometric datasets of the past twenty years (1990–2011). The results show that over northern high latitudes, between 55° and 70°N, UV irradiances at 305 nm decreased significantly by 3.9% per decade, whereas UV irradiance at 325 nm remained stable with no significant long-term change. Over southern high latitudes (55°–70°S), UV irradiances did not show any significant long-term changes at either 305 or 325 nm. Changes in solar UV irradiances are discussed in the context of long-term ozone and other atmospheric parameters affecting UV variability at ground level.

高纬度地区过去20年臭氧和紫外光谱辐射的变化

摘要:本研究分析了位于两个半球高纬度地区的305和325 nm太阳紫外线辐照度的变化。选址受限于过去20年(1990-2011年)最完整的紫外光谱辐射数据集的可用性。结果表明，在55°~ 70°N的北部高纬度地区，305 nm处的紫外线辐照度每10年显著下降3.9%，而325 nm处的紫外线辐照度保持稳定，长期变化不显著。在南方高纬度地区(55°-70°S)，紫外线辐照度在305或325 nm处没有任何显著的长期变化。在影响地面紫外线变率的长期臭氧和其他大气参数的背景下，讨论了太阳紫外线辐照度的变化。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
