Abstract

• Leaf area index (LAI) and green area index (GAI) are fundamental plant traits. However, there is a lack of ground observation network for LAI/GAI due to technical limitations. Here we present a new method to achieve continuous LAI/GAI monitoring using ordinary cameras.
• By tilting ordinary cameras by 30°, images can cover a large view zenith angle range to measure multi-angular gap fractions and thus to quantify LAI using radiative transfer theory. In addition, using cameras can separate green tissues from non-green tissues. We conducted intensive experiments to evaluate the performance of 30°-tilted cameras and built a countywide LAI/...  more
