Title: Plant health observation using OLCI data
Researchers from the DG Joint Research Centres have used OLCI surface reflectance to derive the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), which is an important parameter to define the status of plant health. It describes the absorption of light across a plant canopy, directly related to primary productivity of plants.
This image, taken on 23 September 2016, shows the radiances taken at top of atmosphere (left) and the corresponding FAPAR (right) over Nebraska (USA). The red regions correspond to agricultural zones for which there is high photosynthetic activity and therefore vegetation productivity, while yellow to white areas indicate a low degree of photosynthetic activity.
