Further if tracer X = S * FFCO2, the ability of X to constrain FFCO2 depends on the space time variability of slope S. See Rivier et al. JGR 2006 for discussion > > FelixRVogel > Indeed, N2O and CH4 are not the best examples. But Miller et al successfully used this approach for CH4. Changed the text to focus anthropogenic tracers like CO, HFCs and CFCs that are well correlated. Extended discussion and included Rivier reference.

In review: Andres et al. "A synthesis of carbon dioxide emissions from fossil-fuel combustion"
by Martin Köchy 13 Feb '12

13 Feb '12

Dear all, Andres et al. have submitted a similar paper as ours to Biogeochemical Discussions. Please keep this in mind when you work on our manuscript. Try to reduce overlap. Andres, R. J., Boden, T. A., Bréon, F.-M., Ciais, P., Davis, S., Erickson, D., Gregg, J. S., Jacobson, A., Marland, G., Miller, J., Oda, T., Olivier, J. G. J., Raupach, M. R., Rayner, P., and Treanton, K.: A synthesis of carbon dioxide emissions from fossil-fuel combustion, Biogeosciences Discuss., 9, 1299-1376, doi:10.5194/bgd-9-1299-2012, 2012. http://www.biogeosciences-discuss.net/9/1299/2012/bgd-9-1299-2012.html This synthesis discusses the emissions of carbon dioxide from fossil-fuel combustion and cement production. While much is known about these emissions, there is still much that is unknown about the details surrounding these emissions. This synthesis explores our knowledge of these emissions in terms of why there is concern about them; how they are calculated; the major global efforts on inventorying them; their global, regional, and national totals at different spatial and temporal scales; how they are distributed on global grids (i.e. maps); how they are transported in models; and the uncertainties associated with these different aspects of the emissions. The magnitude of emissions from the combustion of fossil fuels has been almost continuously increasing with time since fossil fuels were first used by humans. Despite events in some nations specifically designed to reduce emissions, or which have had emissions reduction as a byproduct of other events, global total emissions continue their general increase with time. Global total fossil-fuel carbon dioxide emissions are known to within 10% uncertainty (95% confidence interval). Uncertainty on individual national total fossil-fuel carbon dioxide emissions range from a few percent to more than 50%. The information discussed in this manuscript synthesizes global, regional and national fossil-fuel carbon dioxide emissions, their distributions, their transport, and the associated uncertainties.

Workshop paper Global CO2 Emissions
by Martin Köchy 09 Feb '12

09 Feb '12

Greetings. It's been a long time since the last version of our paper. I am sorry (and responsible) for the delay. Now I have a compiled a new version that I would like to ask you to review. I have tried to forge the chapters into one piece. So some of your paragraphs and sentences are now mingling with those of other co-authors. Please check if the content still makes sense. Some sections should be bolstered by references. Considering the length of the manuscript, you should rather delete than add when you work on the manuscript. I have made the document available on google docs so we can see each other's comments and changes. I am also attaching a Word file for those who prefer working offline. If you could work on the manuscript within the next four weeks that would be great.
