Oxygen isotopic signature of CO2 from combustion processes
Oxygen isotopic CO2 combustion processes
2011/2/25
For a comprehensive understanding of the global carbon cycle precise knowledge of all processes is necessary. Stable isotope (13C and 18O) abundances provide information for the qualification and the ...
Atmospheric Processes Influencing Aerosols Generated by Combustion and the Inference of Their Impact on Public Exposure: A Review
Combustion-generated aerosols Vehicle emissions Semi-volatile aerosols Atmospheric process Public health
2016/3/29
Combustion-generated aerosols, especially emissions of heavy and light duty vehicles, are the dominant contributors of
ambient particulate matter (PM) in urban environments. This paper reviews the at...
In-cloud processes of methacrolein under simulated conditions – Part 2: Formation of secondary organic aerosol
In-cloud processes simulated conditions secondary organic aerosol
2009/8/7
The fate of methacrolein in cloud evapo-condensation cycles was experimentally investigated. To this end, aqueous-phase reactions of methacrolein with OH radicals were performed (as described in Liu e...
Equatorial total column of nitrous oxide as measured by IASI on MetOp-A: implications for transport processes
Equatorial total column nitrous oxide IASI MetOp-A
2009/6/22
In this paper we use the total columns of nitrous oxide (N2O) as retrieved from the radiance spectra as measured by the Infrared Atmospheric Sounding Interferometer (IASI) instrument aboard the MetOp-...
The governing processes and timescales of stratosphere-to-troposphere transport and its contribution to ozone in the Arctic troposphere
stratosphere-to-troposphere transport ozone Arctic troposphere
2009/5/15
We used the seasonality of a combination of atmospheric trace gases and idealized tracers to examine stratosphere-to-troposphere transport and its influence on tropospheric composition in the Arctic. ...
Coupling aerosol-cloud-radiative processes in the WRF-Chem model: Investigating the radiative impact of elevated point sources
Coupling aerosol-cloud-radiative processes WRF-Chem model elevated point sources
2009/3/13
The local and regional influence of elevated point sources on summertime aerosol forcing and cloud-aerosol interactions in northeastern North America was investigated using the WRF-Chem community mode...

Simulation of trace gas convective clouds - Liquid phase processes
2009/3/12
A two-dimensional dynamic cloud model with detailed microphysics and a spectral treatment of gas scavenging was used to simulate trace gas vertical redistribution in precipitating continental and mar...
Role of the NO3 radicals in oxidation processes in the eastern Mediterranean troposphere during the MINOS campaign
NO3 radicals oxidation processes eastern Mediterranean troposphere
2009/2/20
During the MINOS campaign (28 July-18 August 2001) the nitrate (NO3) radical was measured at Finokalia station, on the north coast of Crete in South-East Europe using a long path (10.4 km) Differentia...
