Biosphere-atmosphere regulations of droughts assessed using microwave and solar-induced fluorescence observations and improved plant water stress representation

This proposal aims at implementing a plant hydraulic model and a new stomatal conductance model in the NOAH LSM and at developing the use of new satellite-derived products (microwave vegetation optical depth -VOD- and sun-induced fluorescence -SIF-) to constrain LSM parameters at the global scale. The new version of the NOAH model will be implemented in the CFSv2. Observed atmospheric variables will be used to validate the added value on the new developments using the multivariate Granger causality and the wavelet analysis statistical techniques.
