Summary fluxes. This table shows first-guess, final estimate,
and imposed fluxes and associated uncertainties, integrated over the
region of interest and averaged over the relevant time period. The
"first guess" and "final estimate" fluxes are the sum of land and
ocean fluxes over the region of interest, excluding fossil and fire
emissions. They represent the prior and posterior, optimized fluxes
respectively. Fossil and fire emissions are prescribed in
CarbonTracker. The "total flux" is the sum of the final estimate,
fossil fuel emissions, and fire fluxes.
Note that fossil fuel emissions can occur over regions
characterized as ocean. This is partly due to real emissions from
international shipping, and partly due to emissions occurring in
coastal land regions that are assigned to the ocean in our coarse 1x1
degree division scheme. The same is true for fossil fuel emissions
over non-optimized regions such as ice, polar deserts, and inland
seas.
