A CO₂–Δ¹⁴CO₂ inversion setup for estimating European fossil CO₂ emissions by C. Gómez-Ortiz, G. Monteil, G. Monteil, S. Basu, S. Basu, M. Scholze

“…We evaluate the inversion system by conducting a series of observing system simulation experiments (OSSEs). We find that in regions with a dense sampling network, such as western/central Europe, adding <span class="inline-formula">Δ¹⁴CO₂</span> observations in an experiment where the prior fossil <span class="inline-formula">CO₂</span> and biosphere fluxes are set to zero allows LUMIA to recover the time series of both categories. …”
