Short summary

We present a dual tracer atmospheric inversion technique to separately estimate biospheric and fossil fuel CO₂ fluxes from atmospheric measurements of CO₂ and ¹⁴CO₂. In addition to estimating monthly regional fossil fuel fluxes of CO₂, this system can also reduce biases in biospheric fluxes that arise in a traditional CO₂ inversion from prescribing a fixed but inaccurate fossil fuel flux.
