From: A considerable fraction of soil-respired CO2 is not emitted directly to the atmosphere
Monthly cumulative soil CO2 efflux (Fsoil) (with uncertainty represented as the standard error) and monthly cumulative soil CO2 efflux, accounting for the CO2 removed from the soil respiration (Rsoil_ARQ, calculated as Rsoil multiplied by 0.9 ± 0.1/ARQ). The values above of each bar indicate the ratio Rsoil_ARQ/Fsoil. The inset figure shows the annual cumulative of Fsoil and Rsoil _ARQ and its uncertainty.
