IBG-2 – Pflanzenwissenschaften
Area of research:
Scientific / postdoctoral posts
The Plant Sciences subinstitute (IBG-2) of the Institute of Bio- and Geosciences (IBG) investigates the dynamics of plant processes and the interaction of plants with the environment. Plant science at Forschungszentrum Jülich plays a leading role at national and international level in the field of plant phenotyping, i.e. in the quantitative and non-invasive recording of structural and functional properties of plants important for agricultural and horticultural plant breeding. In this context, we are developing new sensors and measurement concepts and integrate them into semi- and fully automated systems. One focus of the subinstitute is the use of optical sensors to promote the automated measurement of plant traits under field conditions. Ground-based measurements are complemented by UAV, aircraft and satellite-based remote sensing approaches. Particular focus is on the development of fluorescence retrieval techniques in preparation of the upcoming Fluorescence Explorer (FLEX) satellite mission of the European Space Agency (ESA).
- Retrieval of solar-induced fluorescence from high performance imaging data
- Development of new algorithms for the preprocessing, atmospheric correction and georectification of airborne hyperspectral data
- Registration of hyperspectral reflectance data with DEMs and DSMs derived from Lidar data
- Adaptation and optimization of fluorescence retrieval schemes from high performance airborne imaging data
- Radiative transfer inversion of leaf and canopy models to derive structural and functional vegetation traits from the combination of airborne imaging spectroscopy data and solar-induced fluorescence
- Interpretation of the results, correlation of remote sensing data with ground based plant traits
