. . "Heiskanen, J." . . . "Monitoring of vegetation by optical remote sensing has undergone development. Physically-based methods generally apply reflectance models for interpreting remotely sensed data sets. These methods have become important in the assessment of terrestrial variables from satellite- and airborne images. Products based on satellite images include various ecological variables that are needed for monitoring changes in forest cover, structure and functioning, including biophysical variables such as the amount of photosynthesizing leaf area. This paper reviews variables and global products estimated from optical satellite sensors describing e.g. the amount and functioning of green biomass and forest carbon exchange. We conclude that continuous validation work as new vegetation products are released continues to be important. We believe that more emphasis is needed on the collection of field data equivalent to satellite retrievals, data harmonization and continuous measurements of forest dynamics." . "0282-7581" . . .
