Mean gross primary productivity (GPP) for the conterminous US and North America in grams of carbon per unit area per month.
Modeled estimates of biogenic CO2 exchanges between land and atmosphere across portions of North America are available.
Mean gross primary productivity (GPP) for the conterminous US and North America in grams of carbon per unit area per month.
Carbon fluxes and uncertainties are available from the Atmospheric Carbon and Transport - America (ACT-America) project.
(A) A Soil Respiration Station (SRS), (B) a SRS data logger, and (C) a Forced Diffusion Chamber (FD chamber) deployed at a boreal forest site in central Alaska.
Data collected by soil respiration stations installed at boreal and tundra sites are available from the Arctic-Boreal Vulnerability Experiment (ABoVE).
Example cross-sections of CO2, O2, and APO (O2 + 1.1 * CO2) measured by AO2 (interpolated flight track data) and the Medusa flask sampler (filled circles) during the Pacific southbound flights of ATom-4 in April and May 2018.
Data collected by the Airborne Oxygen Instrument (AO2) during the Atmospheric Tomography (ATom) airborne campaigns are now available.
Study domain indicating locations of estuaries and shelf waters in the three subregions: the Gulf of Maine (GOM), the Mid-Atlantic Bight (MAB), and the South Atlantic Bight (SAB; From Najjar et al. 2018).
New data from the North American Carbon Program (NACP) provide mean annual carbon fluxes in coastal areas of Eastern North America.
