- Ok, non mettere GeoTOP
- Try to turn temperature map to lastest view

- Change the research questions. Update maps with latest results. Add assumptions: Distributed models need distributed data to be validated. only plot scale observations are not enough. 2. LST is a quantity easily measurable trough remote sensing. 3. LST is a key (and very) variable of the energy budget and if the model is able to correctly reproduce observed LST it is likey that it is able to give a good estimation of ET
- negative skewness

- Validation of the hydrological model at the plot scale <-> field activities Development of grassland growth model for different types of grasslands managements <-> field activities Retrospective simulation at catchment scale <-> streamflow, remote sensing data Future scenarios simulation <-> land management and Regional climate model scenarios Identification of critical variations of key parameters: evapo transpiration, soil moisture, groundwater recharge, runoff production, plant water stress, grassland productivity <-> local scale impacts
