Using Spaceborne Lidar to Improve Climate Models

From this paper by two Korean researchers: “Canopy height is closely related to biomass and aerodynamic properties, which regulate turbulent transfer of energy and mass at the soil-vegetation-atmosphere continuum. However, this key information has been prescribed as a constant value … Continue reading
