Detecting Forest Water‐Availability and Biomass Patterns Through a Retrospective Study in a Mediterranean Region

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Latent heat (λ $\lambda $ET) fluxes are a major component of the hydrological cycle globally. According to recent models and experimental observations, during droughts, wetter regions respond by increasing λ $\lambda $ET, while drier regions exhibit decreasing trends due to vegetation water stress.
