Formation of secondary aerosols over Europe: comparison of two gas-phase chemical mechanisms
secondary aerosols Europe two gas-phase chemical mechanisms
2011/2/24
The impact of two recent gas-phase chemical kinetic mechanisms (CB05 and RACM2) on the formation of secondary inorganic and organic aerosols is compared for simulations of PM2.5 over Europe between 15...
Comparison of global inventories of CO emissions from biomass burning derived from remotely sensed data
CO biomass burning remotely sensed data
2010/12/28
The objective is to highlight similarities and differences by focusing on the geographical and temporal distribution and on the emissions for three broad land cover classes (forest, savanna/grassland ...
Comparison between simulated and observed chemical composition of fine aerosols in Paris (France) during springtime: contribution of regional versus continental emissions
chemical composition fine aerosols springtime regional versus continental emissions
2010/12/28
Hourly concentrations of inorganic salts (ions) and carbonaceous material in fine aerosols (aerodynamic diameter, A.D. <2.5 μm) have been determined experimentally from fast measurements performed for...
Hydroxyl radicals in the tropical troposphere over the Suriname rainforest: comparison of measurements with the box model MECCA
Hydroxyl radicals the tropical troposphere the Suriname rainforest the box model MECCA
2010/10/21
As a major source region of the hydroxyl radical OH, the Tropics largely control the oxidation capacity of the atmosphere on a global scale. However, emissions of hydrocarbons from the tropical rainfo...

Surface noontime spectral ultraviolet (UV) irradiances during May-September of 2000–2004 from the total ozone mapping spectrometer (TOMS) satellite retrievals are systematically compared with the grou...
Improved measurement of carbonaceous aerosol: evaluation of the sampling artifacts and inter-comparison of the thermal-optical analysis methods
carbonaceous aerosol the sampling artifacts the thermal-optical analysis methods
2010/9/21
The sampling artifacts (both positive and negative) and the influence of thermal-optical methods (both charring correction method and the peak inert mode temperature) on the split of organic carbon (O...
Comparison of a global-climate model to a cloud-system resolving model for the long-term response of thin stratocumulus clouds to preindustrial and present-day aerosol conditions
a global-climate model a cloud-system resolving model thin stratocumulus clouds present-day aerosol conditions
2010/8/16
The response of a case of thin, warm marine-boundary-layer (MBL) clouds to preindustrial (PI) and present-day (PD) conditions is simulated by a cloud-system resolving model (CSRM). Here, both the aero...
The global SF6 source inferred from long-term high precision atmospheric measurements and its comparison with emission inventories
the global SF6 source long-term high precision atmospheric measurements emission inventories
2010/8/12
Emissions of sulphur hexafluoride (SF6), one of the strongest greenhouse gases on a per molecule basis, are targeted to be collectively reduced under the Kyoto Protocol. Because of its long atmospheri...
Cloud processing of mineral dust: direct comparison of cloud residual and clear sky particles during AMMA aircraft campaign in summer 2006
