The RCP greenhouse gas concentrations and their extensions from 1765 to 2300
- M. Meinshausen, S. Smith, +10 authors D. Vuuren
- Environmental Science
- 9 August 2011
We present the greenhouse gas concentrations for the Representative Concentration Pathways (RCPs) and their extensions beyond 2100, the Extended Concentration Pathways (ECPs). These projections… Expand
On the global distribution, seasonality, and budget of atmospheric carbonyl sulfide (COS) and some similarities to CO2
- S. Montzka, P. Calvert, +4 authors C. Sweeney
- Environmental Science
- 16 May 2007
[1] Measurements of carbonyl sulfide (COS) from a global air-monitoring network over multiple years suggest that atmospheric mixing ratios of COS are strongly influenced by terrestrial vegetation in… Expand
Small Interannual Variability of Global Atmospheric Hydroxyl
- S. Montzka, M. Krol, E. Dlugokencky, B. Hall, P. Jöckel, J. Lelieveld
- Chemistry, Medicine
- Science
- 7 January 2011
The abundance of the highly reactive hydroxyl radical is well buffered against perturbations. The oxidizing capacity of the global atmosphere is largely determined by hydroxyl (OH) radicals and is… Expand
Anthropogenic emissions of methane in the United States
- Scot M. Miller, S. Wofsy, +12 authors C. Sweeney
- Environmental Science, Medicine
- Proceedings of the National Academy of Sciences
- 25 November 2013
Significance Successful regulation of greenhouse gas emissions requires knowledge of current methane emission sources. Existing state regulations in California and Massachusetts require ∼15%… Expand
A decline in tropospheric organic bromine
- S. Montzka, J. Butler, B. D. Hall, D. Mondeel, J. Elkins
- Environmental Science, Geology
- 1 August 2003
[1] Recent changes in atmospheric bromine (Br) are estimated from samples collected at ten globally distributed, ground-based sites. The results indicate that the global tropospheric burden of Br… Expand
Ruminants, climate change and climate policy
- W. Ripple, P. Smith, H. Haberl, S. Montzka, C. Mcalpine, Douglas H. Boucher
- Environmental Science
- 2014
Greenhouse gas emissions from ruminant meat production are significant. Reductions in global ruminant numbers could make a substantial contribution to climate change mitigation goals and yield… Expand
A record of atmospheric halocarbons during the twentieth century from polar firn air
Measurements of trace gases in air trapped in polar firn (unconsolidated snow) demonstrate that natural sources of chlorofluorocarbons, halons, persistent chlorocarbon solvents and sulphur… Expand
Evolution of alkyl nitrates with air mass age
- S. Bertman, J. M. Roberts, +6 authors H. Westberg
- Geology
- 20 November 1995
Alkyl nitrates (RONO2) and alkanes (RH) were measured at Scotia, Pennsylvania, in 1988 and at the Kinterbish Wildlife Area, Alabama, in 1992. A simple kinetic analysis was developed to relate the two… Expand
Toward a better understanding and quantification of methane emissions from shale gas development
- D. R. Caulton, P. Shepson, +10 authors B. R. Miller
- Engineering, Medicine
- Proceedings of the National Academy of Sciences
- 14 April 2014
Significance We identified a significant regional flux of methane over a large area of shale gas wells in southwestern Pennsylvania in the Marcellus formation and further identified several pads with… Expand
Recent decreases in fossil-fuel emissions of ethane and methane derived from firn air
- M. Aydin, K. Verhulst, +5 authors M. Prather
- Environmental Science, Medicine
- Nature
- 11 August 2011
Methane and ethane are the most abundant hydrocarbons in the atmosphere and they affect both atmospheric chemistry and climate. Both gases are emitted from fossil fuels and biomass burning, whereas… Expand
