water stress

Context: Land surface temperatures (LST) can be sensed from space. They reflect climatic conditions at the land surface (air temperature, radiation), and surface properties. The clue is that they also reflect to what extent water vapour fluxes cool surfaces and that plants have a strong influence on them.

Context: Drone-based yperspectral imaging of vegetation has the potential to identify plant water stress across the landscape. It is hypothesised that at this scale, effects by limited moisture availability in the rooting zone are not evenly distributed and potentially relate to topographic gradients and vegetation-groundwater connectivity.
