Observing Photosynthesis from Space

Observing Photosynthesis from Space

Thursday, 8 March 2018 - 11:00am to 12:00pm

Through photosynthesis plants remove atmospheric carbon dioxide (CO2), storing the carbon as biomass. The fate of this stored carbon partly determines the amount of CO2 in the atmosphere, now and into the future. Current estimates of global terrestrial photosynthesis vary by about a factor of two therefore limiting our understanding of the carbon cycle as a whole. Recent satellite measurements of a phenomenon termed chlorophyll fluorescence now provide us with an unprecedented window into this carbon flux. This thesis examines how these measurements can be combined with a process-based land surface model using a data assimilation system to estimate global terrestrial photosynthesis. This includes uncertainty analysis, comparison with other estimates and insights into improving the model.

Alex is an environmental scientist with experience across a range of fields. He graduated from RMIT University in early 2014 with a double undergraduate degree and honours degree in environmental science and environmental engineering. He has also had short stints working for a water management authority in rural Victoria and in environmental consulting. This allowed him to gain experience across topics including atmospheric and soil chemistry, mathematics, hydrology and environmental modelling. His interest in how humans affect the global environment has prompted Alex to pursue scientific research and undertake a PhD at the University of Melbourne studying the global carbon cycle.
