Extended Data Fig. 7: Relationships between evaporative fraction (EF) and soil volumetric water content (VWC) across eddy covariance sites.
From: When and where soil dryness matters to ecosystem photosynthesis
Critical soil moisture threshold are identified for forests (a), savannahs-shrublands (b), and grasslands (c) using linear-plateau models (see Methods). n indicates the number of sites involved in the analysis. The fitted parameters are statistically significant (two-sided, P < 0.001).
