Land‐atmosphere feedbacks, in particular the response of land evaporation to vapor
pressure deficit (VPD) or the dryness of the air, remain poorly understood. Here we
investigate the VPD response by analysis of a large database of eddy covariance flux

Data analysis reveals that under high VPD and corresponding high temperatures, forest in
