Carbon Storage in Tropical Forests

forest canopy in Pongara National Park, Gabon, West Africa

This image shows the height of the forest canopy for a portion of the Pongara National Park along the Gabon Estuary in Gabon, West Africa. This area includes some of the tallest mangrove forests in the world, indicated by a dark green color, where trees tower up to 60 meters (200 feet). The data were estimated by fusion of PolInSAR and LiDAR data collected by the AfriSAR campaign in March 2016.

NASA’s AfriSAR campaign measured forest structure in Gabon, West Africa to inform estimates of forest carbon storage capacity.

AVIRIS-NG Spectra from ABoVE

Hyperspectral imagery captured for ABoVE during a flight of the AVIRIS-NG instrument

Hyperspectral imagery captured for ABoVE during a flight of the AVIRIS-NG instrument over the Alaskan Arctic.

Surface reflectance was measured along more than 400 flight lines during the intensive 2017 ABoVE airborne campaign.
