CREAF

CREAF runs an annual programme of seminars that showcase the global research work in the field of ecological science both within and beyond our centre. ​Each seminar normally lasts 30-40 minutes with plenty of time afterwards for questions and discussion. Seminars are usually on Wednesday at 3 pm.

TITLE

"Combining proximal sensing and flux measurements to detect physiological and structural response of vegetation in manipulation experiments"

SUMMARY

Hyperspectral remote sensing can be used to directly infer variation in structure and function of the vegetation under different environmental conditions or stress. Among the variety of products, sun-induced fluorescence (SIF)  provides a new non-invasive measurement approach that has the potential to quantify dynamic changes in light-use efficiency and photosynthetic carbon dioxide uptake (Gross Primary Production, GPP). However, the mechanistic link between GPP and sun-induced fluorescence under different environmental conditions, and in particular stress, is not completely understood. In this contribution I will show the structural and functional factors controlling the emission of SIF in a series of manipulative experiment. I will also show the potential of the use of SIF retrieved in the red and far red to determine environmental stress on vegetation.

BIOGRAPHY

Mirco Migliavacca is a scientist at the Max-Planck-Institute for Biogeochemistry (MPI-BGC), leader of the Biosphere-Atmosphere Experimentation and Interaction group within the Department Biogeochemical Integration. His primary interest is in the understanding of the global carbon cycle. His expertise is in the field of biometeorology, eddy covariance flux time series analysis, and earth observation and proximal sensing. For more information click here.
