Climate-carbon cycle feedback analysis: Results from the C
Eleven coupled climate–carbon cycle models used a common protocol to study the coupling between climate change and the carbon cycle. The models were forced by historical emissions and theExpand

Recent patterns and mechanisms of carbon exchange by terrestrial ecosystems
Knowledge of carbon exchange between the atmosphere, land and the oceans is important, given that the terrestrial and marine environments are currently absorbing about half of the carbon dioxide thatExpand

Towards robust regional estimates of CO2 sources and sinks using atmospheric transport models
Information about regional carbon sources and sinks can be derived from variations in observed atmospheric CO2 concentrations via inverse modelling with atmospheric tracer transport models. AExpand

How positive is the feedback between climate change and the carbon cycle?
Future climate change induced by atmospheric emissions of greenhouse gases is believed to have a large impact on the global carbon cycle. Several offline studies focusing either on the marine or onExpand

Reconstructing the recent carbon cycle from atmospheric CO2, δ13C and O2/N2 observations*
This paper presents an attempt to recover the space–time structure of fluxes of CO 2 to the atmosphere over the period 1980–1995 from atmospheric concentration and isotopic composition measurements.Expand

Contribution of the Orbiting Carbon Observatory to the estimation of CO2 sources and sinks: Theoretical study in a variational data assimilation framework
[1] NASA's Orbiting Carbon Observatory will monitor the atmospheric concentrations of carbon dioxide (CO2) along the satellite subtrack over the sunlit hemisphere of the Earth for more than 2 years,Expand

TransCom 3 inversion intercomparison: Impact of transport model errors on the interannual variability of regional CO2 fluxes, 1988–2003
Monthly CO2 fluxes are estimated across 1988–2003 for 22 emission regions using data from 78 CO2 measurement sites. The same inversion (method, priors, data) is performed with 13 differentExpand

Transcom 3 inversion intercomparison: Model mean results for the estimation of seasonal carbon sources and sinks
[1] The TransCom 3 experiment was begun to explore the estimation of carbon sources and sinks via the inversion of simulated tracer transport. We build upon previous TransCom work by presenting theExpand

On aggregation errors in atmospheric transport inversions
This paper explores the consequences of resolution of surface fluxes on synthesis inversions of carbon dioxide. Synthesis inversion divides the Earth's surface into a set of regions and solves forExpand

TransCom 3 CO2 inversion intercomparison: 1. Annual mean control results and sensitivity to transport and prior flux information
Spatial and temporal variations of atmospheric CO2 concentrations contain information about surface sources and sinks, which can be quantitatively interpreted through tracer transport inversion.Expand
