Forest Carbon Across the Western USA

Above ground live tree carbon.

Annual estimates of aboveground live tree carbon (g/m2) as simulated with the Community Land Model (4.5) at 1/24-degree (4 km x 4 km) resolution.

The North American Carbon Program provides new, annual, estimated forest carbon budgets for the Western USA from 1979 to 2099.

Dr. Lucy Hutyra uses NASA data to study the cycling of carbon, especially in urban environments.

Uncertainty in Arctic Carbon Stocks and Fluxes

Uncertainty of carbon stock across the ABoVE domain.

Uncertainty in soil carbon stocks and gross primary productivity across the ABoVE domain.

Work from NASA's ABoVE compared model outputs to estimate the uncertainty in six components of the carbon cycle across Alaska and Canada.

Does Boreal Wildfire Release "Old" Carbon?

Radiocarbon concentration over time according to soil depth and stand age

Radiocarbon concentration (delta14C) in the atmosphere over time, showing the bomb peak in 1966 (red dotted line) and theoretical positions of delta14C of soil depth increments (points).

Researchers with NASA's ABoVE field campaign measured soil and forest stand age at burned sites in Canada's Northwest Territories.

Ecosystem Functional Types Across the USA

Ecosystem functional type (EFT) categories

Spatial distribution of 64 ecosystem functional type (EFT) categories across the conterminous United States (CONUS). For each pixel, the dominant EFT is reported.

New data from the Carbon Monitoring System classifies ecosystems based on their similar ecosystem functioning.
