Assessment of Water Stress Conditions in Central Italy by the Use of Ground and Remotely Sensed Weather Datasets

Aridity and drought, which are determined by climatic temporary water scarcity, respectively, important limiting factors for plant gross primary production. These phenomena commonly assessed and/or monitored means of weather indices, most based on observations precipitation potential evapotranspiration. The estimation such indices over large areas can be carried out using multiple datasets, i.e., those derived from stations, satellite images, ground radars. possibility interpolated or remotely sensed datasets in place measurements was currently investigated Tuscany, a region Central Italy, showing complex heterogeneous environmental features. former were first evaluated versus corresponding measurements. Next, the basic variables combined cumulated 30–60 days to yield synthetic indicators deficit, same way. Finally, these predict soil conditions meadow an olive grove during 2021 summer period. results obtained indicate that use multi-source induces only minor deterioration stress is therefore efficient monitor status different ecosystems with high spatial (200 m) temporal (daily) details.
