Gridded uncertainty in fossil fuel carbon dioxide emission maps, a CDIAC example [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Due to a current lack of physical measurements at appropriate spatial and temporal scales, all current global maps and distributions of fossil fuel carbon dioxide (FFCO2) emissions use one or more proxies to distribute those emissions.

Journal Staff [PDF]

open access: yes, 1959
Water and supercritical carbon dioxide have different wetting angles to a glass surface, where water has a lower angle. In a microfluidic channel, the lower wetting angle draws the water to surround the supercritical carbon dioxide and the supercritical ...

A new evaluation of the uncertainty associated with CDIAC estimates of fossil fuel carbon dioxide emission [PDF]

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2014
Three uncertainty assessments associated with the global total of carbon dioxide emitted from fossil fuel use and cement production are presented. Each assessment has its own strengths and weaknesses and none give a full uncertainty assessment of the ...
