Role of forest structure in the up-scaling of canopy reflectance and solar-induced chlorophyll fluorescence
Annotation in Czech
The project will contribute to the ongoing COST Action CA17134 – SENSECO, which brings together international research community working on synergies in Earth Observation data and up-scaling of ecophysiological vegetation traits. The main focus of the project will be optimization of the radiative transfer modeling of coniferous (spruce) forest as a key to detailed understanding of solar-induced chlorophyll fluorescence (SIF) emission and light scattering inside the forest canopy. The 3D structure of forest canopies influences light scattering properties and such as modified the signal recorded by remote sensing sensors. Our motivation is to provide a complex 3D environment that will allow for detailed sensitivity analysis in structurally complex coniferous forests. The project will be divided into three parts. The first part will be focused on the improvement and modification of an existing algorithm for 3D spruce tree representation that was developed by the proponent team. We will particularly focus on modeling of 3D needle shoots from detailed laboratory laser scans and adjust the needle shoots for detailed sensitivity studies, as well as for extensive simulations. The second part will be focuses on detailed sensitivity study on how forest 3D structure and optical properties influences the subtle signal of SIF and the up-scaling to satellite data. The third part will focus on more effective use of DART simulated spectra in ARTMO (Automated Radiative Transfer Models Operator) through model emulation.
