Remote Sensing Of Terrestrial Ecosystems

全球碳循环是指大气、海洋和陆地之间的碳交换。与大气和海洋碳循环相比，人们对陆地碳循环的了解更少，这是造成全球碳预算估算误差最大的原因。这主要是由于缺乏对CO2施肥对植物生长的影响程度和植物生长对变暖胁迫的敏感性变化的认识。Gonsamo博士的研究项目将整合碳循环模型和直接测量光合作用的新兴卫星技术，以提高对光合作用过程的了解，减少陆地碳循环估算的不确定性。

The global carbon cycle is the exchange of carbon among the atmosphere, oceans and land. The land carbon cycle is less understood than either the atmosphere and ocean carbon cycles, contributing the largest error to the global carbon budget estimates. This is attributed largely to the lack of understanding of the magnitude of CO2 fertilization effect on plant growth and the changing sensitivity of plant growth to warming-induced stress. Dr. Gonsamo¿s research program will integrate carbon cycle models and emerging satellite technologies that directly measure photosynthesis for improved insight into photosynthetic processes to reduce the land carbon cycle estimation uncertainty.
