Energy partitioning between surface latent (LE) and sensible (H) heat fluxes is a key factor in the development of the boundary layer and the regulation of the hydrological cycle. Climate factors and surface cover are commonly considered the major controlling effects on energy partitioning. However, the influence of other drivers such as water table depth and groundwater convergence has rarely been considered.
Here, we use an extensive dataset of eddy covariance and global remote-sensing data to show that not only climate, but also water table depth and plant functional type (PFT) play an important role in energy partitioning across different biomes. Our findings illuminate the understanding of plant water stress in terrestrial ecosystems.
