Our new paper is out on Nature Plants! We found that soil moisture contributes more to ecosystem photosynthesis than VPD for the water-limited periods and water-limited locations, using causality-guided explainable AI. www.nature.com/articles/s41...

When and where soil dryness matters to ecosystem photosynthesis - Nature Plants
Using a causality-guided explainable AI framework, Liu et al. show soil moisture dominates vapour pressure deficit in shaping global photosynthesis during water-limited conditions.
