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.

全球碳循环是碳在大气、海洋和陆地之间的交换。陆地碳循环比大气和海洋碳循环了解得更少，是全球碳预算估计的最大误差。这在很大程度上归因于缺乏对CO2施肥对植物生长影响的程度以及植物生长对变暖诱导的胁迫的敏感性变化的理解。贡萨莫博士的研究计划将整合碳循环模型和新兴的卫星技术，直接测量光合作用，以提高对光合作用过程的洞察力，以减少陆地碳循环估计的不确定性。
