Compound-specific stable carbon and hydrogen isotopic compositions of n-alkanes in urban atmospheric aerosols from Tokyo
δD, δ13C, n-alkane urban aerosols Tokyo
2017/8/9
Stable carbon (δ13C) and hydrogen (δD) isotopic compositions of n-alkanes in total suspended particles from Tokyo were measured to decipher their source and transport in the polluted urban atmosphere....
Molecular hydrogen (H2) emissions and their isotopic signatures (H/D) from a motor vehicle: implications on atmospheric H2
Molecular hydrogen (H2) isotopic signatures (H/D) a motor vehicle atmospheric H2
2010/8/13
Molecular hydrogen (H2), its isotopic signature (deuterium/hydrogen, δD), carbon monoxide (CO), and other compounds were studied in the exhaust of a passenger car engine fuelled with gasoline or metha...
Atmospheric hydrogen variations and traffic emissions at an urban site in Finland
Atmospheric hydrogen variations traffic emissions Finland
2009/10/9
Atmospheric hydrogen (H2) mixing ratios were observed over a one year period from summer 2007 to 2008 in Helsinki, Finland. Relatively stable background values of hydrogen were occasionally observed a...
We report measurements of the deuterium content of molecular hydrogen (H2) obtained from a suite of air samples that were collected during a stratospheric balloon flight between 12 and 33 km at 40&ord...
The overwhelming role of soils in the global atmospheric hydrogen cycle
soil global atmospheric hydrogen cycle molecular hydrogen
2009/1/7
The removal of molecular hydrogen (H2) from the atmosphere is dominated by the uptake in soils. Notwithstanding, estimates of the magnitude of this important process on a global scale are highly uncer...
The tropospheric processing of acidic gases and hydrogen sulphide in volcanic gas plumes as inferred from field and model investigations
tropospheric processing acidic gases hydrogen sulphide volcanic gas plumes
2008/12/3
Improving the constraints on the atmospheric fate and depletion rates of acidic compounds persistently emitted by non-erupting (quiescent) volcanoes is important for quantitatively predicting the envi...
Hydrogen isotope fractionation in the photolysis of formaldehyde
Hydrogen isotope fractionation in the photolysis of formaldehyde
2008/10/31
Experiments investigating the isotopic fractionation in the formation of H2 by the photolysis of CH2O under tropospheric conditions are reported and discussed. The deuterium (D) depletion in the H2 pr...
