Chemical, physical, and optical evolution of biomass burning aerosols: a case study
biomass burning aerosols Chemical physical
2011/2/25
In-situ chemical composition measurements of ambient aerosols have been used for characterizing the evolution of submicron aerosols from a large anthropogenic biomass burning (BB) event in Israel. A h...
Chemical evolution of secondary organic aerosol from OH-initiated heterogeneous oxidation
Chemical evolution secondary organic aerosol OH-initiated heterogeneous oxidation
2010/8/13
The heterogeneous oxidation of laboratory Secondary Organic Aerosol (SOA) particles by OH radicals was investigated. SOA particles, produced by reaction of α-pinene and O3, were exposed to OH radicals...

2009/10/9
Measurements of aerosol composition were made with an Aerodyne High Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) on board the NSF/NCAR C-130 aircraft as part of the Intercontinenta...
Evolution of stratospheric ozone and water vapour time series studied with satellite measurements
stratospheric ozone water vapour time series satellite measurements
2009/8/25
The long term evolution of stratospheric ozone and water vapour has been investigated by extending satellite time series to April 2008. For ozone, we examine monthly average ozone values from various ...
Technical Note: Evolution, current capabilities, and future advance in satellite nadir viewing ultra-spectral IR sounding of the lower atmosphere
current capabilities ultra-spectral IR sounding lower atmosphere
2009/8/7
Infrared ultra-spectral spectrometers have brought in a new era in satellite remote atmospheric sounding capability. During the 1970s, after the implementation of the first satellite sounding instrume...
East Asian SO2 pollution plume over Europe – Part 2: Evolution and potential impact
East Asian SO2 pollution Europe Evolution potential impact
2009/7/23
We report on the first observation-based case study of an aged East Asian anthropogenic SO2 pollution plume over Europe. Our airborne measurements in that plume detected highly elevated SO2 mole fract...
Evolution of NOx emissions in Europe with focus on road transport control measures
NOx emissions Europe road transport control measures
2009/3/13
European emission trends of nitrogen oxides since 1880 and up to present are presented here and are linked to the evolution of road transport emissions. Road transport has been the dominating source o...
Modelling the evolution of organic carbon during its gas-phase tropospheric oxidation: development of an explicit model based on a self generating approach
organic carbon gas-phase tropospheric oxidation explicit model self generating approach
2009/2/17
Organic compounds emitted in the atmosphere are oxidized in complex reaction sequences that produce a myriad of intermediates. Although the cumulative importance of these organic intermediates is wide...
