Remote Sensing of Leaf Area Index and Primary Productivity

Indian Institute of Technology, Kharagpur and NPTEL via Swayam


The leaf area index (LAI) is a response parameter for photosynthesis as it directly relates to the light interception and gas exchange through the stomata. It is a dimensionless biophysical variable, which is calculated as the ratio of leaf area to per unit ground surface area. Monitoring of the LAI provides an understanding of dynamic changes in productivity, climate impacts on terrestrial ecosystems, energy balance, canopy water interception, and gas exchange. Therefore, understanding of the LAI is a crucial parameter for physiological, ecological, and climatological studies.INTENDED AUDIENCE : UG and PG students of Agriculture, Forest and ecological sciences and engineeringPRE REQUISITE :NoneSUPPORTED INDUSTRIES : All Industries working in Agriculture, Forest, Ecology,Environment and Climate domain
