AfriSAR

Tropical Forest Biomass in Gabon

Aboveground biomass.

Aboveground biomass mapped at 0.25 ha resolution for the Mondah study site in Gabon, West Africa.

The AfriSAR campaign produced maps of aboveground biomass for four forested sites in Gabon based on field data and LiDAR scans.

Three-dimensional maps of forest structure in Gabon are now available from the 2016 AfriSAR campaign.

Carbon Storage in Tropical Forests

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.

Tree data, canopy cover, and vertical profile metrics from forests in Gabon have been published.

NASA's AfriSAR campaign provides critical data on canopy height and structure of tropical forests in Gabon, West Africa.
