Extended Data Fig. 5: Dependencies of Causal Shapley values under energy-limited conditions.
From: When and where soil dryness matters to ecosystem photosynthesis
a-p, Relationships between Causal Shapley values and SW, TA, VPD, and SM for eddy covariance measurements across biomes of forests (a–d), drylands (e–h), and grasslands (i–l), as well as TROPOMI SIF observations over global humid regions (m–p). Causal Shapley values are presented in consistent units with the eddy covariance half-hourly GPP data (µmol m−2 s−1, a–l) and TROPOMI SIF (mWm−2 sr−1 nm−1, m–p). SW: incoming shortwave radiation; TA: air temperature; VPD: vapour pressure deficit; VWC: volumetric water content.
