The global methane budget 2000–2012
Abstract. The global methane (CH4) budget is becoming an increasingly important component for managing realistic pathways to mitigate climate change. This relevance, due to a shorter atmosphericExpand

Global and regional emissions estimates for N 2 O
Abstract. We present a comprehensive estimate of nitrous oxide (N2O) emissions using observations and models from 1995 to 2008. High-frequency records of tropospheric N2O are available fromExpand

Growth Rate, Seasonal, Synoptic, Diurnal Variations and Budget of Methane in the Lower Atmosphere
We have used an AGCM (atmospheric general circulation model)-based Chemistry Transport Model (ACTM) for the simulation of methane (CH4) in the height range of earth’s surface to about 90 km. TheExpand

Emissions of carbon tetrachloride from Europe
Abstract. Carbon tetrachloride (CCl4) is a long-lived radiatively active compound with the ability to destroy stratospheric ozone. Due to its inclusion in the Montreal Protocol on Substances thatExpand

History of atmospheric SF 6 from 1973 to 2008
We present atmospheric sulfur hexafluoride (SF 6) mole fractions and emissions estimates from the 1970s to 2008. Measurements were made of archived air sam- ples starting from 1973 in the NorthernExpand

Historical greenhouse gas concentrations for climate modelling (CMIP6)
TLDR
We provide consolidated datasets of historical atmospheric concentrations (mole fractions) of 43 GHGs to be used in the Climate Model Intercomparison Project – Phase 6 (CMIP6) experiments. Expand

Perfluorocarbons in the global atmosphere: tetrafluoromethane, hexafluoroethane, and octafluoropropane
Abstract. We present atmospheric baseline growth rates from the 1970s to the present for the long-lived, strongly infrared-absorbing perfluorocarbons (PFCs) tetrafluoromethane (CF4), hexafluoroethaneExpand

Characterization of uncertainties in atmospheric trace gas inversions using hierarchical Bayesian methods
We present a hierarchical Bayesian method for at- mospheric trace gas inversions. This method is used to esti- mate emissions of trace gases as well as "hyper-parameters" that characterize theExpand

Nitrous oxide emissions 1999 to 2009 from a global atmospheric inversion
Abstract. N2O surface fluxes were estimated for 1999 to 2009 using a time-dependent Bayesian inversion technique. Observations were drawn from 5 different networks, incorporating 59 surface sites andExpand
