Atmospheric Sulfate Particles Reduced,but as Acidic as Ever（图）
Atmospheric Sulfate Particles Reduced Acidic as Ever
2016/3/2
Something very similar is happening in the atmosphere. Acidic sulfur emissions from power plants have been rapidly declining over the past decade, and the neutralizing base – ammonia – is emitted from...
Impact of mineral dust on nitrate, sulfate, and ozone in transpacific Asian pollution plumes
mineral dust nitrate sulfate ozone transpacific Asian pollution plumes
2010/8/12
We use a 3-D global chemical transport model (GEOS-Chem) to interpret aircraft observations of nitrate and sulfate partitioning in transpacific dust plumes during the INTEX-B campaign of April–May 200...
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...
Depositional ice nucleation on solid ammonium sulfate and glutaric acid particles
Depositional ice nucleation solid ammonium sulfate glutaric acid particles
2010/3/16
Heterogeneous ice nucleation on solid ammonium sulfate and glutaric acid particles was studied using optical microscopy and Raman spectroscopy. Optical microscopy was used to detect selective nucleati...
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...
Impact of palmitic acid coating on the water uptake and loss of ammonium sulfate particles
palmitic acid ammonium sulfate particles
2009/2/12
While water insoluble organics are prevalent in the atmosphere, it is not clear how the presence of such species alters the chemical and physical properties of atmospheric aerosols. Here we use a com...
Parameterization of N2O5 reaction probabilities on the surface of particles containing ammonium, sulfate, and nitrate
N2O5 sulfate nitrate
2008/11/19
A parameterization was developed for the heterogeneous reaction probability (γ) of N2O5 as a function of temperature, relative humidity (RH), particle composition, and phase state, for use in advanced...
Calibration and measurement uncertainties of a continuous-flow cloud condensation nuclei counter (DMT-CCNC): CCN activation of ammonium sulfate and sodium chloride aerosol particles in theory and experiment
calibration continuous-flow cloud condensation nuclei counter CCN sodium chloride aerosol
2008/10/31
Experimental and theoretical uncertainties in the measurement of cloud condensation nuclei (CCN) with a continuous-flow thermal-gradient CCN counter from Droplet Measurement Technologies (DMT-CCNC) ha...
