Forest Attributes from Radar Interferometric Structure and Its Fusion with Optical Remote Sensing

I mportant ecological processes are expressed in and are affected by the vertical structure of forest canopies. Chief among these processes is the carbon cycle, the uncertainties in which limit understanding of climatic trends over the next century. Changes in vegetation structure, induced by climatic conditions, natural disturbance, and human activities, can have substantial impacts on carbon storage and the exchange of carbon dioxide (CO 2 ), water vapor, and heat with the atmosphere
