DESDynI (Deformation, Ecosystem Structure and Dynamics of Ice) is a NASA satellite mission that will provide global estimates of aboveground biomass and ecosystem structure using LiDAR (Light Detection and Ranging) and L-band radar. LiDAR waveforms and radar backscatter coefficients at different wave polarizations are sensitive to forest height, structure, and composition, and can be used to make quantitative estimates of standing biomass/carbon stocks and ecosystem structure for biodiversity and habitat assessment. Field and aircraft observations in support of DESDynI for terrestrial ecosystem science have been collected at the La Selva Biological Station in Costa Rica, in the Sierra Nevada and New England regions of the USA. DESDynI Airborne simulators include the Laser Vegetation Imaging Sensor (LVIS) and Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR), which provide full waveform LiDAR returns and quad polarization L-band radar data, respectively. Ground-based data include forest inventories; leaf reflectance spectrum; and vertical/horizontal distribution of canopy elements by visual observation, hemispheric photography, and ground-based LiDAR. This presentation provides a description of these measurements and ongoing research studies, as well as links to the data and key science contacts.
