Three-dimensional climatological distribution of tropospheric OH: Update and evaluation

A global climatological distribution of tropospheric OH is computed using observed distributions of O3, H2O, NOt (NO2 +NO + 2N2O5 + NO3 + HNO2 +HNO4), CO, hydrocarbons, temperature, and cloud optical…

Carbon 13 and D kinetic isotope effects in the reactions of CH4 with O(1 D) and OH: New laboratory measurements and their implications for the isotopic composition of stratospheric methane

Measurements of the 13C and D kinetic isotope effects (KIE) in methane, 13CKIE = k(12CH4)/k(13CH4) and DKIE = k(12CH4)/k(12CH3D), in the reactions of these atmospherically important methane…

The Indian Ocean Experiment: Widespread Air Pollution from South and Southeast Asia

It is shown that agricultural burning and especially biofuel use enhance carbon monoxide concentrations and Fossil fuel combustion and biomass burning cause a high aerosol loading, which gives rise to extensive air quality degradation.

Oxygen isotope composition of stratospheric carbon dioxide

Heavy oxygen isotope enrichment in stratospheric CO2 has been identified in the past as a direct result of the large O3 isotope anomaly though no simultaneous measurements are known. Results from 8…

Complete and accurate mass spectrometric isotope analysis of tropospheric nitrous oxide

[1] We describe a manual extraction and purification method for mass spectrometric isotope analyses of tropospheric N2O. A theoretical framework to correct for (hydro)fluorocarbon and CO2…

The overwhelming role of soils in the global atmospheric hydrogen cycle

The removal of molecular hydrogen (H2) from the atmosphere is dominated by the uptake in soils. Notwith- standing, estimates of the magnitude of this important pro- cess on a global scale are highly…

Atmospheric CH4 in the first decade of the 21st century: Inverse modeling analysis using SCIAMACHY satellite retrievals and NOAA surface measurements

The causes of renewed growth in the atmospheric CH4 burden since 2007 are still poorly understood and subject of intensive scientific discussion. We present a reanalysis of global CH4 emissions…

Significant radiative impact of volcanic aerosol in the lowermost stratosphere

It is shown that half of the global stratospheric aerosol optical depth following the Kasatochi, Sarychev and Nabro eruptions is attributable to LMS aerosol, and that the LMS makes an important contribution to the overall volcanic forcing.
