Research Spotlight: Estimating forest rainfall interception from satellite observations


  • Ernie Tretkoff


Although most rainfall over continents reaches the ground, a significant portion is caught by the forest canopy and evaporates directly. To better understand feedbacks between evaporation and climate and to estimate the effects of climate change and deforestation on water resources, scientists need to know how much rainfall is intercepted by the canopy. Miralles et al. applied satellite rainfall data to an existing model to create global maps of estimated forest rainfall interception.
