Understanding Sun-Sensor Geometry Effects in Solar Induced Fluorescence Observations for Better Remote Sensing of Photosynthetic Carbon Uptake
Min Chen is an assistant professor in the Department of Forest and Wildlife Ecology at UW-Madison.
Remotely sensed solar-induced chlorophyll fluorescence (SIF) has been increasingly used as a proxy of large-scale vegetation photosynthetic carbon uptake (i.e., Gross Primary Productivity; GPP). However, similar to other remote sensing metrics, SIF observations are subject to sun-sensor geometry effects which can lead to considerable uncertainties in various uncertainties. This seminar will discuss the underlying processes of the sun-sensor geometry effects on SIF, methods of minimizing these effects and potential applications by taking advantages of these effects for better quantifying GPP.
