The Total Carbon Column Observing Network
Debra Wunch,Geoffrey C. Toon,Jean-Francois Blavier,Rebecca A. Washenfelder,Justus Notholt,Brian J. Connor,David W. T. Griffith,Vanessa Sherlock,Paul O. Wennberg +8 more
TL;DR: The TCCON provides a link between satellite measurements and the extensive ground-based in situ network and achieves an accuracy and precision in total column measurements that is unprecedented for remote-sensing observations.
Journal ArticleDOI

Wennberg,Nicholas M. Deutscher,Nicholas M. Deutscher,David W. T. Griffith,R. Macatangay,J. Messerschmidt,Justus Notholt,Thorsten Warneke +21 more
TL;DR: In this paper, the column-average dry air mole fractions of atmospheric carbon dioxide and methane are inferred from observations of backscattered sunlight conducted by the Greenhouse gases Observing SATellite (GOSAT).

TL;DR: A review of the advances in stratospheric aerosol research can be found in this article, with a focus on the agreement between in situ and space-based inferences of aerosol properties during volcanically quiescent periods.
Journal ArticleDOI

TL;DR: In this paper, a large number of isotopic data sets (four satellite, sixteen ground-based remote-sensing, five surface in situ and three aircraft data sets) are analyzed to determine how H2O and HDO measurements in water vapor can be used to detect and diagnose biases in the representation of processes controlling tropospheric humidity in atmospheric general circulation models (GCMs).

TL;DR: In this paper, a method of evaluating systematic errors in measurements of total column dry-air mole fractions of CO2 (XCO2) from space is described, and applied to the v2.8 Atmospheric CO2 Observations from Space retrievals of the Greenhouse Gases Observing Satellite (ACOS-GOSAT) measurements over land.
