متن کاملGlobal modelling of secondary organic aerosol
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract A global 3-dimensional chemistry/transport model able to describe O 3 , NO x , Volatile Organic Compounds (VOC), sulphur and NH 3 chemistry has been extended to simulate the temporal and spatial distribution of primary and secondary carbonaceous aerosols ...
متن کاملGlobal secondary organic aerosol from isoprene oxidation
[1] Inclusion of isoprene as a source of secondary organic aerosol (SOA) in a global model increases the global burden of SOA from all sources by more than a factor of two. The isoprene source substantially increases SOA concentrations in the free troposphere, because isoprene, and, more importantly, isoprene’s oxidation products, have much greater concentrations at higher altitudes than other ...
متن کاملMeasurements of secondary organic aerosol from oxidation of cycloalkenes, terpenes, and m-xylene using an Aerodyne aerosol mass spectrometer.
The Aerodyne aerosol mass spectrometer (AMS) was used to characterize physical and chemical properties of secondary organic aerosol (SOA) formed during ozonolysis of cycloalkenes and biogenic hydrocarbons and photo-oxidation of m-xylene. Comparison of mass and volume distributions from the AMS and differential mobility analyzers yielded estimates of "effective" density of the SOA in the range o...
