Optical remote sensing of ecosystems at regional to global scales

Professor Gregory Asner
Geological & Environmental Science Stanford University


Ecosystems are under ever increasing pressure from human activities, either directly via land use or indirectly via changes in atmospheric composition. Measurement and monitoring of Earth's ecosystems requires a synoptic view, which can only be achieved through large-scale remote sensing observations. Most remote sensing of ecosystems occurs in the optical, thermal and radar domains. Of these domains, the optical remote sensing capabilities are currently the most advanced for ecosystem studies. Some of the major developments are being achieved by tapping the full spectral, temporal and angular reflectance information that is now available from airborne and spaceborne sensors. These advances will be presented, with particular attention to the major global change issues facing Earth scientists today. Examples will be drawn from global carbon cycle, deforestation and desertification research ongoing at the Carnegie Institution located at Stanford University.
