Carbon flux, in the context of biogeochemical topics, denotes the rate at which carbon in its various chemical forms (e.g., CO₂, CH₄, dissolved inorganic and organic carbon, particulate organic carbon) is transferred per unit area and time between reservoirs such as the atmosphere, terrestrial biosphere, oceans, and lithosphere. It encompasses processes including photosynthetic uptake, respiration, decomposition, combustion, weathering, ocean–atmosphere gas exchange, and sedimentation. Quantification of carbon fluxes, typically in units like g C m⁻² yr⁻¹, is central to constraining carbon budgets, modeling the global carbon cycle, and assessing feedbacks in climate system research.
