Ram Oren
Nicholas Professor of Earth Systems Science

With his graduate students, Dr. Oren quantifies the components of water flux in forest ecosystems and the influence of biotic and abiotic factors on water and, due to strong links between carbon and water, on carbon flux. Climate variability, including variations in air temperature, vapor pressure deficit, incoming radiation and soil moisture, and environmental change, including elevated atmospheric carbon dioxide, affect the intra- and inter-annual patterns and amounts of water used by forest ecosystems, and its spatial distribution, as well as carbon uptake and sequestration. The variation of water flux influence the temporal and spatial partitioning of incoming radiation between latent and sensible heat. Using a local mass balance approach and detailed measurements of water flux and driving variables in the soil, plants, and the atmosphere, in forests from Brazil to Alaska, Dr. Oren evaluates the likely responses of different forest ecosystems to environmental change.
