Aerosol analysis using a Thermal-Desorption Proton-Transfer-Reaction Mass Spectrometer (TD-PTR-MS):a new approach to study processing of organic aerosols
Aerosol analysis Thermal-Desorption Proton-Transfer-Reaction Mass Spectrometer organic aerosols
2010/3/5
We present a novel analytical approach to measure the chemical composition of organic aerosol. The new instrument combines proton-transfer-reaction mass-spectrometry (PTR-MS) with a collection-thermal...

mineral dust cloud residual AMMA aircraft campaign
2010/2/21
In order to gain insights into the characteristics of the mineral dust particles incorporated in the actual cloud droplets and the related cloud processing, the French ATR-42 research aircraft equippe...
Latitudinal variation in the multiphase chemical processing of inorganic halogens and related species over the eastern North and South Atlantic Oceans
Latitudinal variation inorganic halogens eastern North and South Atlantic Oceans
2009/10/9
Volatile inorganic and size-resolved particulate Cl- and Br-species were measured in near-surface air over a broad range of conditions within four distinct regimes (European – EURO, North African – N-...
Cloud processing, cloud evaporation and Angström exponent
Cloud processing cloud evaporation Angströ m exponent
2009/3/12
With a cloud parcel model we investigate how cloud processing and cloud evaporation modify the size distribution and the Angström exponent of an aerosol population. Our study provides a new expla...

Aerosol particles Mexican East Pacific vertical redistribution
2009/1/14
Airborne measurements of aerosol particle size distributions were made in the Mexican Intertropical Convergence Zone. The volume concentrations of submicron and super micron particles at cloud base w...
Processing of soot in an urban environment: case study from the Mexico City Metropolitan Area
Processing of soot urban environment Mexico City Metropolitan Area
2009/1/14
Chemical composition, size, and mixing state of atmospheric particles are critical in determining their effects on the environment. There is growing evidence that soot aerosols play a particularly imp...

Aerosol activation cloud processing global aerosol-climate model
2009/1/12
A parameterization for cloud processing is presented that calculates activation of aerosol particles to cloud drops, cloud drop size, and pH-dependent aqueous phase sulfur chemistry. The parameterizat...
The influence of nitric acid on the cloud processing of aerosol particles
influence of nitric acid cloud processing of aerosol particles
2009/1/7
In this paper we present simulations of the effect of nitric acid (HNO3) on cloud processing of aerosol particles. Sulfuric acid (H2SO4) production and incloud coagulation are both affected by condens...
