GEDI 2019

In May-June 2019, the NASA LVIS Facility and LVIS Classic were deployed to sites in the Southeastern United States as well as Central America as part of an airborne campaign to provide calibration and validation of the recently-launched Global Ecosystem Dynamics Investigation (GEDI) payload on the International Space Station. During the three week deployment of LVIS, a total of 5 flights were flown over diverse science targets based out of Ellington Field in Houston, TX. Flight trajectories and preliminary coverage maps are available on this page.
