**Summary**: The Global Ecosystem Dynamics Investigation, or GEDI, instrument on the International Space Station acquires lidar waveforms to observe the Earth’s surface in 3D. The GEDI lidar measures the height and density of objects, so it provides information such as surface elevation and tree canopy height and cover. The NASA Land Processes Distributed Active Archive Center (LP DAAC) at EROS provides storage and distribution of GEDI data.  In this episode, we’ll take a look at the purpose of the GEDI mission, how the instrument works, and how GEDI data are being used to understand things like carbon dynamics in forests.

**Guests:**Ralph Dubayah and Laura Duncanson, University of Maryland and the GEDI mission

**Host:** Jane Lawson

**Producer:** Tom Adamson
