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.

TL;DR: In this article, a global Bayesian variational inversion of CO2 surface fluxes during the period 1988-2008 is presented, where weekly fluxes are estimated on a 3.75 degrees x 2.5 degrees (longitude-latitude) grid throughout the 21 years.

Euan G. Nisbet,Edward J. Dlugokencky,Martin R. Manning,David Lowry,Rebecca Fisher,S. E. Michel,John B. Miller,John B. Miller,James W. C. White,Bruce H. Vaughn,Philippe Bousquet,John A.

Wolff,Anita L. Ganesan +24 more
TL;DR: The isotopic evidence presented in this article suggests that the methane rise was dominated by significant increases in biogenic methane emissions, particularly in the tropics, for example, from expansion of tropical wetlands in years with strongly positive rainfall anomalies or emissions from increased agricultural sources such as ruminants and rice paddies.

Observations and modelling of the global distribution and long-term trend of atmospheric 14CO2
Ingeborg Levin,Tobias Naegler,Bernd Kromer,Moritz Diehl,Roger J. Francey,A. J. Gomez-Pelaez,L. Paul Steele,Dietmar Wagenbach,Rolf Weller,Douglas E. J. Worthy +9 more
TL;DR: In this paper, high-precision atmospheric Δ 14 CO 2 records covering the last two decades are presented, and evaluated in terms of changing (radio)carbon sources and sinks, using the coarse-grid carbon cycle model GRACE.
