9317120戈蒂埃，将在各种空间和时间尺度上调查南极表面紫外线和光合作用活性辐照度的收支情况。该项目将继续正在进行的测绘工作，以确定大面积地理区域表面辐照度的空间变异性。最大比例尺地图将覆盖整个南极海岸线和南大洋，分辨率为50公里。将为进行广泛生物研究的地区以及极地涡旋动力学表明重要辐射现象的地区绘制更高空间分辨率的地图。将扩大和改进卫星测绘，纳入确定冰缘的微波卫星数据，并利用蒙特卡罗辐射传输方法进行更多种类的云模拟。实地工作将包括于1994年春季在南极洲帕尔默站安装一个新开发的传感器网络，以加强那里的国家科学基金会紫外线监测网络仪器。该项目将首次研究南极半岛雪、海冰和海洋表面在紫外线下的反照率，并将为物理和生物科学家提供重要成果。***

9317120 Gautier The budget of Antarctic surface ultraviolet and photosynthetically active irradiance will be investigated over a variety of spatial and temporal scales. This project will continue ongoing mapping work to characterize the spatial variability of surface irradiance over large geographical areas. The largest scale maps will cover the entire Antarctic coastline and Southern Ocean at a fifty kilometer resolution. Higher spatial resolution maps will be constructed for areas where extensive biological research is conducted, and for areas where polar vortex dynamics suggest important radiative phenomena. Satellite mapping will be augmented and refined by incorporating microwave satellite data for ice edge determination and by utilizing Monte Carlo radiative transfer methods to enable a greater variety of cloud simulations. Field work will include the installation during the austral spring of 1994 at Palmer Station, Antarctica a network of newly developed sensors to augment the National Science Foundation Ultraviolet Monitoring Network instrumentation there. This project will be the first to study the albedo of Antarctic peninsular snow, sea ice, and ocean surfaces in the ultraviolet and will provide important results for both physical and biological scientists. ***
