The Global Ecosystem Dynamics Investigation (GEDI) instrument has paused acquisition of science data for a period of 13 to 18 months in anticipation of it’s move to an alternate location on the International Space Station (ISS).
Last month, NASA issued the following statement regarding the GEDI mission aboard the ISS:
The ISS offers a unique hosting opportunity for Earth science payloads where NASA can test new instrument approaches that can make major contributions to understanding the changing planet.
NASA’s GEDI instrument aboard the space station is one of multiple instruments from the agency and others providing information about the Earth system and effects of climate change.
Demand is high for external operations on station, and GEDI is scheduled to be replaced by a Department of Defense (DOD) payload after more than four years of operations. However, the agency is exploring an option to keep the instrument in space through the life of the space station.
The proposed solution calls for temporarily moving GEDI to an alternate location, where it will remain offline while a DOD’s technology payload completes its mission. In 2024, GEDI will return to its original location, and resume operations on station.
A link for the Digital Object Identifier (DOI) landing page for each of the GEDI datasets available through LP DAAC is provided below.
GEDI L1B Geolocated Waveform Data Global Footprint Level - GEDI01_B
GEDI L2A Elevation and Height Metrics Data Global Footprint Level - GEDI02_A
GEDI L2B Canopy Cover and Vertical Profile Metrics Data Global Footprint Level - GEDI02_B
GEDI data products in the LP DAAC archive remain available for distribution through the Data Pool and NASA’s Earthdata Search.
