Anthropogenic sulfur dioxide emissions: 1850–2005
Sulfur aerosols anthropogenic global regional sulfur dioxide
2011/2/25
Sulfur aerosols impact human health, ecosystems, agriculture, and global and regional climate. A new annual estimate of anthropogenic global and regional sulfur dioxide emissions has been constructed ...
Long term measurements of sulfur dioxide, nitrogen dioxide, ammonia, nitric acid and ozone in Africa using passive samplers
sulfur dioxide nitrogen dioxide ammonia nitric acid ozone Africa passive samplers
2010/8/16
In this paper we present the long term monitoring of ambient gaseous concentrations within the framework of the IDAF (IGAC-DEBITS-AFRICA) program. This study proposes for the first time an analysis of...
Sulfur dioxide emissions in China and sulfur trends in East Asia since 2000
Sulfur dioxide China sulfur trends East Asia
2010/8/16
With the rapid development of the economy, the sulfur dioxide (SO2) emission from China since 2000 is of increasing concern. In this study, we estimate the annual SO2 emission in China after 2000 usin...
Sulfur cycle and sulfate radiative forcing simulated from a coupled global climate-chemistry model
Sulfur cycle sulfate radiative a coupled global climate-chemistry model
2010/8/12
The sulfur cycle and radiative effects of sulfate aerosol on climate are studied with a Global tropospheric Climate-Chemistry Model in which chemistry, radiation and dynamics are fully coupled. Produc...
Initial fate of fine ash and sulfur from large volcanic eruptions
Initial fate fine ash large volcanic eruptions
2009/12/3
Large volcanic eruptions emit huge amounts of sulfur and fine ash into the stratosphere. These products cause an impact on radiative processes, temperature and wind patterns. In simulations with a Gen...
Closing the dimethyl sulfide budget in the tropical marine boundary layer during the Pacific Atmospheric Sulfur Experiment
dimethyl sulfide budget tropical marine boundary layer Pacific Atmospheric Sulfur Experiment
2009/11/19
Fourteen research flights were conducted with the National Center for Atmospheric Research (NCAR) C-130 near Christmas Island (2° N, 157° W) during the summer of 2007 as part of the Pacific Atmospheri...
An emission inventory of sulfur from anthropogenic sources in Antarctica
emission inventory sulfur anthropogenic sources Antarctica
2009/6/2
This paper presents first results of a comprehensive emission inventory of chemical species from anthropogenic activities (power generation, vehicles, ships and aircraft) in Antarctica, covering the 2...
Variable CCN formation potential of regional sulfur emissions
Variable CCN formation potential regional sulfur emissions
2009/6/2
Aerosols are short lived so their geographical distribution and impact on climate depends on where they are emitted. Previous model studies have shown that the mass of sulfate aerosol produced per uni...
Gaseous（DMS, MSA, SO2, H2SO4 and DMSO）and particulate（sulfate and methanesulfonate）sulfur species over the northeastern coast of Crete
MSA SO2 H2SO4 DMSO northeastern coast of Crete
2009/3/11
A detailed study of the levels, the temporal and diurnal variability of the main compounds involved in the biogenic sulfur cycle was carried out in Crete (Eastern Mediterranean) during the Mediterrane...
Kinetics and mechanism of heterogeneous oxidation of sulfur dioxide by ozone on surface of calcium carbonate
Kinetics and mechanism heterogeneous oxidation sulfur dioxide calcium carbonate
2009/1/12
Sulfate particles play a key role in the air quality and the global climate, but the heterogeneous formation mechanism of sulfates on surfaces of atmospheric particles is not well established. Carbona...
Nanoparticle formation in the exhaust of vehicles running on ultra-low sulfur fuel
exhaust of vehicle sulfur fuel
2008/11/17
The concern of adverse health impacts from exposure to vehicle-emitted nanoparticles has been escalating over the past few years. In order to meet more stringent EPA emission standards for particle ma...
Estimation of the vertical profile of sulfur dioxide injection into the atmosphere by a volcanic eruption using satellite column measurements and inverse transport modeling
sulfur dioxide volcanic eruption
2008/11/13
An analytical inversion method has been developed to estimate the vertical profile of SO2 emissions from volcanic eruptions. The method uses satellite-observed total SO2 columns and an atmospheric tra...
Source-receptor relationships between East Asian sulfur dioxide emissions and Northern Hemisphere sulfate concentrations
Source-receptor East Asian sulfur dioxide Northern Hemisphere
2008/11/13
We analyze the effect of varying East Asian (EA) sulfur emissions on sulfate concentrations in the Northern Hemisphere, using a global coupled oxidant-aerosol model (MOZART-2). We conduct a base and f...
Analysis of aircraft and satellite measurements from the Intercontinental Chemical Transport Experiment (INTEX-B) to quantify long-range transport of East Asian sulfur to Canada
