The overarching goal of EO-WAVE is to reduce uncertainties in our knowledge on how soil moisture drives vegetation growth over space and time.Using long-term Earth Observation datasets of the water and carbon cycles we will try to address two major scientific challenges: Scientific Challenge 1 (SC1) will seek an answer to the question “How does soil moisture drive vegetation growth?” while Scientific Challenge 2 (SC2) addresses the question “How does climate change affect the relationship between soil moisture and vegetation”?
In particular, the project targets the following objectives:
1. Empirically quantify the effect of drought on vegetation growth.
2. Identify key deficiencies in water-vegetation interaction in state-of-the-art Earth System Models and provide observational support for improving the parameterisation of processes in these models.
3. Identify changes in vegetation dynamics (trends and extremes) over time and quantify the relative role of water availability herein.
A schematic overview of the project structure and tasks is given below.
