Carbon flux is the direction and rate of transfer — or flow — of carbon between Earth’s carbon pools, such as the oceans, atmosphere, land, and living things. Carbon fluxes can be natural exchanges, such as land-atmosphere and ocean-atmosphere fluxes. The can also be human-triggered exchanges, such as urban carbon fluxes occurring within the built environment involving fossil fuel use and other processes. Understanding and tracking carbon flux is part of increasing our knowledge of Earth's carbon cycle and how it affects ecosystem function, plant growth, and climate.

NASA offers carbon flux data derived from multiple sources including computer models and the versatile Moderate Resolution Imaging Spectroradiometer (MODIS) and Global Ecosystem Dynamics Investigation (GEDI) lidar instruments.
