The Global Ecosystem Dynamics Investigation, or GEDI, measures the 3D structure of Earth from the International Space Station using near-infrared lasers.  The data that GEDI collects are immensely valuable for improving our understanding of the world's forests and complex carbon cycles. In this presentation, GEDI scientist Adrian Pascual and research assistant Tali Schwelling, will talk about GEDI mission status, future challenges and goals, the exciting ways in which GEDI is being used by scientists and stakeholders today, and why GEDI is important for studying trees even in our own backyards. Following the featured presentation, Peder Nelson will bring us back to the GEDI data-rich Global Forest Canopy Height online tool. Towards the end of the webinar, we will revisit the call, from the February 14 webinar, to all our campaign students (and teachers) about interviewing elders in the local community about the local changes in land cover and tree height over the last 10, 20, 50 years.
