California Fossil Fuel CO2 Emissions

Total CO2 concentrations and fossil fuel CO2 concentrations

Seasonal quartiles of total CO2 concentrations and fossil fuel CO2 concentrations for each of the nine observation sites in California, 2014-2015.

CMS: Atmospheric CO2 and C Isotopes, Fossil Fuel Contributions, California, 2014-2015

This new dataset from the NASA Carbon Monitoring System (CMS) provides atmospheric measurements of CO2 concentrations, the contributions of fossil fuel CO2 (ffCO2), and carbon isotopes d13C and D14C from nine observation sites in California for three month-long campaigns in separate seasons of 2014-2015. Observed and simulated ffCO2 were incorporated into Bayesian inverse estimates of ffCO2. Inverse estimates of total in-state ffCO2 emissions are consistent with the California Air Resources Board’s reported ffCO2 emissions, providing tentative validation of California’s reported ffCO2 emissions in 2014–15.

The NASA Carbon Monitoring System (CMS) is designed to make significant contributions in characterizing, quantifying, understanding, and predicting the evolution of global carbon sources and sinks through improved monitoring of carbon stocks and fluxes.
