A Climatology of Biologically Active Sunlight for the High Latitude Southern Hemisphere and Argentina

这个项目将为南半球高纬度地区、南纬55度的极地地区和阿根廷发展一个多年的地球表面太阳紫外线辐射气候学。感兴趣的光谱区域为290至400 nm加上与海洋生物学和人类健康相关的作用光谱的卷积。所述的时间段将是1979年至至少1992年，并在获得新数据时稍后。该方法将以太阳辐射传输的数值模型为基础，使用测量的大气吸收和散射特性作为输入。具体来说，光轮7号卫星携带的总臭氧测绘光谱仪提供了近紫外波段柱臭氧和云反照率的信息。来自阿根廷乌斯怀亚国家科学基金会光谱辐射计和计划中的阿根廷辐射网的太阳辐照度测量将用于评价并在必要时改进对由卫星数据产生的云量的处理。将特别关注每年南极臭氧损耗解体后的时间段。* * *

9314616 Frederick This project will develop a multi-year climatology of solar ultraviolet radiation at the earth's surface for the high latitudes of the Southern Hemisphere, poleward of 55os, and the country of Argentina. The spectral region of interest is 290 to 400 nm plus convolutions with action spectra of relevance to marine biology and human health. The time period addressed will be 1979 through at least 1992, and later as new data become available. The approach will be based on a numerical model of solar radiation transfer using measured absorption and scattering properties of the atmosphere as inputs. Specifically, the Total Ozone Mapping Spectrometer carried on the Nimbus 7 satellite provides information on both column ozone and cloud albedos in the near ultraviolet. Solar irradiance measurements from NSF spectroradiometer at Ushuaia, Argentina and from the planned Argentine radiation network will be used to evaluate and, if needed, to improve the treatment of cloudiness developed from the satellite data. Special attention will focus on the time period after the breakup of each year's Antarctic ozone depletion. ***
