Journal ArticleDOI
Increase in observed net carbon dioxide uptake by land and oceans during the past 50 years
Ashley P. Ballantyne,Caroline B. Alden,John B. Miller,John B. Miller,Pieter P. Tans,James W. C. White,James W. C. White +6 more
TL;DR: Global-scale atmospheric CO2 measurements, CO2 emission inventories and their full range of uncertainties are used to calculate changes in global CO2 sources and sinks during the past 50 years and show that net global carbon uptake has increased significantly and thatglobal carbon uptake doubled between 1960 and 2010.
Journal ArticleDOI
Multi-element regulation of the tropical forest carbon cycle
TL;DR: In this paper, the authors address the problem of understanding how nutrients control the tropical carbon cycle and incorporate such knowledge into predictive models for predicting how ecosystems will respond to climate and other environmental changes.
Journal ArticleDOI
Regional trace-gas source attribution using a field-deployed dual frequency comb spectrometer
Sean Coburn,Caroline B. Alden,Robert J. Wright,Kevin C. Cossel,Esther Baumann,Gar-Wing Truong,Fabrizio R. Giorgetta,Colm Sweeney,Nathan R. Newbury,Kuldeep R. Prasad,Ian Coddington,Gregory B. Rieker +11 more
TL;DR: In this article, a dual frequency comb laser spectrometer was deployed for the first time, enabling an observing system that provides continuous detection of trace-gas sources over multiple square-kilometer regions.
Journal ArticleDOI
Audit of the global carbon budget: estimate errors and their impact on uptake uncertainty
Ashley P. Ballantyne,Robert J. Andres,Richard A. Houghton,Benjamin D. Stocker,Rik Wanninkhof,William R. L. Anderegg,Leila Cooper,Michael D. DeGrandpre,Pieter P. Tans,John B. Miller,Caroline B. Alden,James W. C. White +11 more
TL;DR: In this paper, a framework for assessing the temporal and spatial components of estimate errors and their impact on uncertainty in net C uptake by the biosphere is presented, based on which a novel approach for incorporating temporally correlated random error into the error structure of emission estimates is proposed.
Journal ArticleDOI

TL;DR: A regional atmospheric CO2 inversion is developed that provides the first analysis of geographic and temporal variability in Amazon biosphere-atmosphere carbon exchange and that is minimally influenced by biosphere model-based first guesses of seasonal and annual mean fluxes.
