This project will address the question of how phytoplankton may impact on the thermal structure and circulation of the upper ocean, and its subsequent effect on the Earth's climate via the absorption of solar radiation and modification of the surface albedo. The approach employs radiative-transfer models, mixed layer and radiative-convective models, ocean and climate general circulation models, and satellite imagery of phytoplankton chlorophyllous pigments. Forcing by phytoplankton will be specified using satellite-derived chlorophyll concentrations derived from existing bio-optical algorithms. The experiments are expected to lead to an improved understanding of the mechanisms generating sea surface temperatures and their influence on the climate.This project is expected to result in an improved understanding of predicting climate change due to carbon dioxide. One graduate student will be supported.

该项目将研究浮游植物如何影响上层海洋的热结构和环流，以及浮游植物通过吸收太阳辐射和改变表层海水而对地球气候产生的影响。该方法采用辐射传输模式，混合层和辐射对流模式，海洋和气候环流模式，以及浮游植物叶绿素色素的卫星图像。浮游植物的强迫将使用从现有生物光学算法推导出的卫星叶绿素浓度来指定。预计这些实验将使人们更好地了解产生海洋表面温度的机制及其对气候的影响，预计该项目将使人们更好地了解预测二氧化碳引起的气候变化。将资助一名研究生。
