Homogeneous nucleation sulfuric acid and water mixture
2010/8/12
In this study we introduce a new flow tube suitable for binary and ternary homogeneous nucleation studies. The production of sulfuric acid and water vapor mixture, the experimental setup and the metho...
Patterns of North African dust transport over the Atlantic: winter vs. summer, based on CALIPSO first year data
North African dust transport Atlantic CALIPSO
2009/11/9
One of the most important factors that determine the transported dust effect on the atmosphere is its vertical distribution. In this study the vertical structure of North African dust and stratiform l...
First steps towards the assimilation of IASI ozone data into the MOCAGE-PALM system
assimilation IASI ozone data MOCAGE-PALM system
2009/8/7
With the use of data assimilation, we study the quality of the Infrared Atmospheric Sounding Interferometer (IASI) total ozone column measurements. The IASI data are provided by the inversion of IASI ...

infrared carbon monoxide analyser commercial Airbus aircraft MOZAIC III programme
2009/3/11
The European-funded MOZAIC programme (Measurements of ozone and water vapour by Airbus in-service aircraft) has been operational since 1994 aboard 5 commercial Airbus A340. It has gathered ozone and w...
New-particle formation events in a continental boundary layer: first results from the SATURN experiment
New-particle formation events continental boundary layer SATURN experiment
2009/3/11
During the SATURN experiment, which took place from 27 May to 14 June 2002, new particle formation in the continental boundary layer was investigated. Simultaneous ground-based and tethered-balloon-bo...
Saharan dust events at the Jungfraujoch: detection by wavelength dependence of the single scattering albedo and first climatology analysis
Saharan dust events Jungfraujoch single scattering albedo climatology analysis
2009/3/10
Scattering and absorption coefficients have been measured continuously at several wavelengths since March 2001 at the high altitude site Jungfraujoch (3580ma.s.l.). From these data, the wavelength dep...
