Fluxes Description

Mean Fluxes : By convention, a positive sign is used for sources of CO2 to the atmosphere and a negative sign for sinks of CO2 from the atmosphere. These fluxes can be directly compared with the results of large-scale independent bottom-up models, inventories of accounting systems.

Flux Anomalies : A long term mean flux “climatology“ over the period is subtracted from either the yearly mean or from the selected monthly mean flux. Flux anomalies maps are especially useful to understand how 'abnormal' was the CO2 balance of a given region during a specific period as compared to its long-term mean value. For instance, the big 1997-1998 El Niño and the drought years at northern mid latitudes in 2002, 2003 and 2005 have caused large anomalies in CO2 fluxes.

Total flux : defined here as the sum of ocean fluxes, land ecosystem exchange and fossil fuel emissions. The Total flux is a direct result of inversions.

Natural fluxes : the difference between the total flux and the fossil emissions.

Ocean fluxes : results from all physical and biological processes responsible for the exchange of CO2 across the air-sea interface.

Land fluxes : defined as the sum of photosynthesis, ecosystem respiration and biomass burning.
