Analysis of UV Radiation Measurements in Antarctica

这项建议的主要目标是利用在国家科学基金会赞助下在南极洲收集的紫外线辐射数据，以提供臭氧和紫外线辐射之间缺失的联系。在地面测量的紫外线辐射与相应的臭氧柱密度之间的关系将被量化。具体而言，该项目将进行以下分析：利用紫外线辐射数据1)根据哈金斯波段波长对的测量强度比确定柱臭氧含量，2)计算紫外线剂量并与臭氧量相关，3)将测量的光谱与详细的辐射传输计算进行比较。计算结果将用于评估其他环境参数，如地面反照率、气溶胶和云对透射紫外线辐射的影响。

The principal objective of this proposal is to utilize the UV radiation data to be gathered under NSF sponsorship in Antarctica to provide the missing link between ozone and UV radiation. The relationship between UV radiation measured at the ground and the corresponding ozone column densities will be quantified. In particular, the project will do the following analysis: Use the UV radiation data to 1) determine the column ozone content from measured intensity ratios for wavelength pairs in the Huggins band, 2) compute UV doses and relate to ozone amounts, 3) compare measured spectra with detailed radiative transfer calculations. The computations will be used to assess the effects of other environmental parameters such as ground albedo, aerosols and clouds on the transmitted UV radiation.
