Carbon flux models

Definition

Carbon flux models are mathematical representations that estimate the movement and exchange of carbon between different components of the Earth's system, including the atmosphere, oceans, and terrestrial ecosystems. These models help in understanding how carbon is stored, released, and transformed within various environmental contexts, providing crucial insights into carbon cycling and its implications for climate change.
