Global Tree Cover and Biomass Carbon on Agricultural Land - 2000-2010
The Global Tree Cover and Biomass Carbon on Agricultural Land Database provides raster data describing percent tree cover and above- and below-ground biomass carbon on agricultural land, globally, at a resolution of 1 km2 (30 arc seconds in geographic coordinates, as provided for online data distribution), for the period 2000 to 2010. These datasets provide the primary results and data used for the geospatial analysis presented in Zomer et al, 2016:
