We present optimized emissions from 1973-present of three perfluorocarbons: tetrafluoromethane (CF4), hexafluoroethane (C2F6) and octafluoropropane (C3F8). The dominant sources of the PFCs are primary aluminum and semiconductor production. CF4 also has a significant pre-industrial abundance from the build-up of very small natural emissions. The inversions were performed with atmospheric measurements made by the Advanced Global Atmospheric Gases Experiment (AGAGE) network as well as using stored samples from the Commonwealth Scientific and Industrial Research Organization (CSIRO) Southern Hemisphere archive and from several Northern Hemisphere sources. Inverse estimates of surface flux were derived from the measurements using a discrete Kalman filter, the annual pulse method of Chen and Prinn (J. Geophys. Res., 111, D10307, doi:10.1029/2005JD006058), and a 2D 12-box chemical transport model. CF4 emissions have decreased from ~20 Gg/yr in 1981 to the present value of ~11 Gg/yr. Conversely, C2F6 and C3F8 exhibit an early increase in emissions, peaking much later around 2000 at ~3 Gg/yr and ~1 Gg/yr, respectively, and subsequently declining. The incongruity in the emission profiles is discussed in the context of different relative emissions of CF4 and the other measured PFCs from the two main sources, efforts by the aluminum industry to reduce the emission factor of CF4 (kg CF4 /ton Al), and published emission inventories. In all cases, over 90% of emissions are from the Northern Hemisphere.
