Description

This dataset provides temporally consistent and harmonized global maps of aboveground and belowground biomass carbon density for the year 2010 at a 300-m spatial resolution. The aboveground biomass map integrates land-cover specific, remotely sensed maps of woody, grassland, cropland, and tundra biomass. Input maps were amassed from the published literature and, where necessary, updated to cover the focal extent or time period. The belowground biomass map similarly integrates matching maps derived from each aboveground biomass map and land-cover specific empirical models. Aboveground and belowground maps were then integrated separately using ancillary maps of percent tree cover and landcover and a rule-based decision tree. Maps reporting the accumulated uncertainty of pixel-level estimates are also provided.

Provider's note: The WCMC carbon biomass dataset represents conditions between 1982 and 2010 depending on land cover type. The relative patterns of carbon stocks are well represented with this dataset. The NASA/ORNL carbon biomass dataset represents biomass conditions for 2010, with uncertainty estimates at the pixel-level. Additional biomass of non-dominant land cover types are represented within each pixel. For more detailed information, please refer to the papers describing each dataset: WCMC (Soto-Navarro et al. 2020) and NASA/ORNL (Spawn et al. 2020).

Bands

Name Units Min Max Description
agb Mg C/ha 0* 129*

Aboveground living biomass carbon stock density of combined woody and herbaceous cover in 2010. This includes carbon stored in living plant tissues that are located above the earth’s surface (stems, bark, branches, twigs). This does not include leaf litter or coarse woody debris that were once attached to living plants but have since been deposited and are no longer living.

agb_uncertainty Mg C/ha 0* 85*

Uncertainty of estimated aboveground living biomass carbon density of combined woody and herbaceous cover in 2010. Uncertainty represents the cumulative standard error that has been propagated through the harmonization process using summation in quadrature.

bgb Mg C/ha 0* 57*

Belowground living biomass carbon stock density of combined woody and herbaceous cover in 2010. This includes carbon stored in living plant tissues that are located below the earth’s surface (roots). This does not include dead and/or dislocated root tissue, nor does it include soil organic matter.

bgb_uncertainty Mg C/ha 0* 37*

Uncertainty of estimated belowground living biomass carbon density of combined woody and herbaceous cover in 2010. Uncertainty represents the cumulative standard error that has been propagated through the harmonization process using summation in quadrature.
