Version Comparison (CT2007B)
How do flux estimates from CarbonTracker CT2007B compare with the previous release (CT2007)?

The tables below summarize the estimated surface fluxes for combined natural sources (Table 1) derived from the current release (CT2007B) and the previous release (CT2007) of CarbonTracker, and those used for fossil fuel burning (Table 2) in both releases. The uncertainty in the estimates is the one standard deviation from the filter estimate. Units are PgC/yr (1015 gC/year, or billion metric ton C/year, or 3.7 billion metric ton CO2/year).

Table 1: Average natural flux (biosphere + ocean + fire) estimated from CT2007B [2001-2006] and CT2007 [2001-2005]. The uncertainty is the one standard deviation from the filter estimate. Units are PgC/yr.
