Vegetation-light Interactions, Biodiversity Measurement from Space

The varying radiation regime has an impact on plant growth. We use physically based models of soil-vegetation-atmosphere transfer (and their inverse) to assess ecosystem level vegetation structure (or architecture) and biochemistry. Focus is on using 1D and 3D radiative transfer models specializing on retrieval of plant pigments (Chl a/b, Carotenoids, Anthocyanin), non-pigments (leaf water), and structure (LAI, leaf inclination angle, etc.). We use in-situ, airborne and spaceborne instruments in combination with inverse modeling of those radiative transfer models to retrieve those parameters. We also improve models of NPP by using advanced Light Use Efficiency (LUE) proxies, including steady-state Chlorophyll fluorescence in the O₂absorption line. We are interested in large scale changes of those parameters, allowing to model spatiotemporal changes of growth limiting factors, biochemistry and structure in a changing environment.
