Simulations of ffCO2 at the sites and times of the observations were conducted with the Vulcan v2.2 fossil fuel emissions estimate for 2002 and the Weather Research and Forecasting - Stochastic Time-Inverted Lagrangian Transport (WRF-STILT) atmospheric model. The observed and simulated ffCO2 were incorporated into Bayesian inverse estimates of ffCO2 to calculate California's ffCO2 emissions during the campaign period.}, publisher={ORNL Distributed Active Archive Center}, author={Graven, H. and Fischer, M.L. and Lueker, T. and Jeong, S. and Guilderson, T.P. and Keeling, R.F. and Bambha, R. and Brophy, K. and Callahan, W. and Cui, X. and Frankenberg, C. and Gurney, K.R. and Lafranchi, B.W. and Lehman, S. and Michelsen, H.A. and Miller, J.B. and Newman, S. and Paplawsky, W. and Parazoo, N.C. and Sloop, C. and Walker, S.J.}, year={2019}, language={en}, }
