Sentinel Image to Estimate Industrial Tomato Leaf Area Index
Brazilian Archives of Biology and Technology, 2023 The Leaf Area Index (LAI) is one of the main physiological parameters of the plant related to transpiration, productivity and rainfall interception. Among the methods to determine the LAI, the use of remote sensing that estimates the LAI through image ...

Projections of leaf area index in earth system models [PDF]
Earth System Dynamics, 2016 The area of leaves in the plant canopy, measured as leaf area index (LAI), modulates key land–atmosphere interactions, including the exchange of energy, moisture, carbon dioxide (CO2), and other trace gases and aerosols, and is therefore an essential ...

Leaf area index retrieval with ICESat-2 photon counting LiDAR
International Journal of Applied Earth Observations and Geoinformation, 2021 This is the first study to inverse leaf area index (LAI) with photon counting LiDAR (i.e., Ice, Cloud, and Land Elevation Satellite-2/Advanced Topographic Laser Altimeter System, ICESat-2/ATLAS). A new framework composed of three major steps was applied:
