GEDI

Example subset of aboveground biomass density (AGBD; Mg ha-1) predictions from the GEDI Level-4A footprint product over Northern California, U.S., spanning April to July 2019. GEDI footprints are spaced 60m along-track and 600m across-track.

The Global Ecosystem Dynamics Investigation (GEDI) instrument provides high resolution laser ranging of Earth's forests and topography from the International Space Station (ISS).

The GEDI instrument onboard the ISS uses three lasers split into eight tracks that fire 242 times per second illuminating a 25-meter footprint of the Earth's surface.

The Find and Use GEDI, You Will—Getting Started with Global Ecosystems Dynamics Investigation (GEDI) Lidar Data webinar will be held on Wednesday, June 24, from 2 to 3 PM EST.

GEDI data will help further refine our understanding of the carbon cycle and atmospheric concentrations of carbon dioxide (CO2).

The GEDI instrument's 80 cm telescope will receive laser-light returning from Earth.
