Department of Environmental Sciences Professor Xi Yang is a coauthor on a study published in the Journal of Geophysical Research – Biogeosciences. The study used the sun-induced fluorescence (SIF) system designed by Prof. Yang to continuously monitor soybean photosynthesis. The increased understanding of the connection between SIF and photosynthesis at the local scale is an important advance towards monitoring photosynthesis globally in real-time using satellite based SIF measurements.
