Most of current general circulation models (GCMs) show a remarkable positive precipitation bias over the southwestern equatorial Indian Ocean (SWEIO), which can be thought of as a westward expansion o...
A secondary organic aerosol formation model considering successive oxidation aging and kinetic condensation of organic compounds: global scale implications
A secondary organic aerosol formation model successive oxidation aging organic compounds global scale
2011/2/25
The widely used two-product secondary organic aerosol (SOA) formation model has been extended in this study to consider the volatility changes of secondary organic gases (SOG) arising from the aging p...
Ground-based remote sensing of an elevated forest fire aerosol layer at Whistler, BC: implications for interpretation of mountaintop chemistry
an elevated forest fire aerosol layer mountaintop chemistry
2010/12/28
On 30 August 2009, intense forest fires in interior British Columbia (BC) coupled with winds from the east and northeast resulted in transport of a broad forest fire plume across southwestern BC. The ...
Some implications of sampling choices on comparisons between satellite and model aerosol optical depth fields
sampling choices satellite and model aerosol optical depth fields
2010/11/30
The comparison of satellite and model aerosol optical depth (AOD) fields provides useful information on the strengths and weaknesses of both. However, the sampling of satellite and models is very diff...
CO2 and its correlation with CO at a rural site near Beijing: implications for combustion efficiency in China
CO2 CO a rural site near Beijing combustion efficiency China
2010/10/11
Although China has surpassed the United States as the world's largest carbon dioxide emitter, in situ measurements of atmospheric CO2 have been sparse in China. This paper analyzes hourly CO2 and its ...
Computation of liquid-liquid equilibria and phase stabilities: implications for RH-dependent gas/particle partitioning of organic-inorganic aerosols
liquid-liquid equilibria phase stabilities RH-dependent gas/particle organic-inorganic aerosols
2010/8/25
Semivolatile organic and inorganic aerosol species partition between the gas and aerosol particle phases to maintain thermodynamic equilibrium. Liquid-liquid phase separation into an organic-rich and ...
Vertical structure of Antarctic tropospheric ozone depletion events: characteristics and broader implications
Vertical structure Antarctic tropospheric ozone depletion events characteristics and broader implications
2010/8/25
The majority of tropospheric ozone depletion event (ODE) studies have focussed on time-series measurements, with comparatively few studies of the vertical component. Those that exist have almost exclu...

Snow-sourced bromine polar tropospheric ozone
2010/8/25
In the last two decades, significant depletion of boundary layer ozone (ozone depletion events, ODEs) has been observed in both Arctic and Antarctic spring. ODEs are attributed to catalytic destructio...
Nanoparticles in boreal forest and coastal environment: a comparison of observations and implications of the nucleation mechanism
Nanoparticles boreal forest coastal environment the nucleation mechanism
2010/8/16
The detailed mechanism of secondary new particle formation in the atmosphere is still under debate. It is proposed that particle formation happens via activation of 1–2 nm atmospheric neutral molecula...
