Remote Sensing Of Terrestrial Ecosystems

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.
