CO2 Concentrations Across North America
New model outputs from the Penn State WRF-Chem version of the Weather Research and Forecasting (WRF) model estimate the hourly CO2 concentration in the atmosphere.
Carbon flux measurements from AirMOSS
New data from NASA's Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) investigation examines carbon fluxes at Duke, Harvard, and Howland Forests.
Biomass loss due to tropical deforestation
New maps show the degree of deforestation in tropical America, Africa, and Asia between 2000 and 2012 and provide estimates of aboveground live biomass loss.
The ORNL DAAC mission is to assemble, distribute, and provide data services for a comprehensive archive of terrestrial biogeochemistry and ecological dynamics observations and models to facilitate research, education, and decision-making in support of NASA’s Earth science.
