TL;DR: In this article, a global mean distribution for surface water pCO2 over the global oceans in non-El Nino conditions has been constructed with spatial resolution of 4° (latitude) × 5° (longitude) for a reference year 2000 based upon about 3 million measurements of surface water PCO2 obtained from 1970 to 2007.
Journal ArticleDOI

TL;DR: In this paper, the Wanninkhof dependence of the CO2 gas transfer velocity has been used to estimate the global ocean CO2 flux in the mean non-El Nino conditions for a reference year 1995.

Wouter Peters,Andrew R. Jacobson,Colm Sweeney,Arlyn E. Andrews,Thomas J. Conway,K. A. Masarie,John B. Miller,Lori Bruhwiler,Gabrielle Pétron,A. Hirsch,Douglas E. J. Worthy,G. R. van der Werf,James T. Randerson,Paul O. Wennberg,Maarten Krol,P. P. Tans +15 more
TL;DR: An estimate of net CO2 exchange between the terrestrial biosphere and the atmosphere across North America for every week in the period 2000 through 2005 is presented, derived from a set of 28,000 CO2 mole fraction observations in the global atmosphere that are fed into a state-of-the-art data assimilation system for CO2 called CarbonTracker.
Journal ArticleDOI
Weak northern and strong tropical land carbon uptake from vertical profiles of atmospheric CO2
Britton B. Stephens,Kevin R. Gurney,Pieter P. Tans,Colm Sweeney,Wouter Peters,Lori Bruhwiler,Philippe Ciais,Michel Ramonet,Philippe Bousquet,Takakiyo Nakazawa,Shuji Aoki,Toshinobu Machida,Gen Inoue,Nikolay K. Vinnichenko,Jon Lloyd,Armin Jordan,Martin Heimann,Olga Shibistova,Ray L. Langenfelds,L. Paul Steele,Roger J. Francey,A. Scott Denning +21 more
TL;DR: Measurements of midday vertical atmospheric CO2 distributions reveal annual-mean vertical CO2 gradients that are inconsistent with atmospheric models that estimate a large transfer of terrestrial carbon from tropical to northern latitudes, suggesting that northern terrestrial uptake of industrial CO2 emissions plays a smaller role than previously thought.
