Modelling multi-phase halogen chemistry in the coastal marine boundary layer: investigation of the relative importance of local chemistry vs. long-range transport
multi-phase halogen chemistry the coastal marine boundary layer local chemistry long-range transport
2011/2/25
Measurements of significant concentrations of IO, I2 and BrO in a semi-polluted coast environment at Roscoff, in North-West France, have been made as part of the Reactive Halogens in the Marine Bounda...
The relative importance of various source regions on East Asian surface ozone
source regions East Asian surface ozone
2010/12/20
We estimated the source-receptor relationship for surface O3 in East Asia during the early 2000s using a method that tags O3 tracers according to their region of chemical production (tagged tracer met...
Global modeling of organic aerosol: the importance of reactive nitrogen (NOx and NO3)
organic aerosol reactive nitrogen (NOx and NO3)
2010/12/20
Reactive nitrogen compounds, specifically NOx and NO3, likely influence global organic aerosol levels. To assess these interactions, GEOS-Chem, a chemical transport model, is updated to include improv...

transport model uncertainties CO2 sources and sinks satellite measurements
2010/11/3
This study presents a synthetic model intercomparison to investigate the importance of transport model errors for estimating the sources and sinks of CO2 using satellite measurements. The experiments ...
The importance of aerosol mixing state and size-resolved composition on CCN concentration and the variation of the importance with atmospheric aging of aerosols
aerosol mixing state size-resolved composition CCN concentration atmospheric aerosols
2010/8/16
Aerosol microphysics, chemical composition, and CCN concentrations were measured at the T0 urban supersite in Mexico City during Megacity Initiative: Local and Global Research Observations (MILAGRO) i...
Effects of resolution on the relative importance of numerical and physical horizontal diffusion in atmospheric composition modelling
numerical and physical horizontal diffusion atmospheric composition modelling
2010/8/12
Numerical diffusion induced by advection has a large influence on concentration of substances in atmospheric composition models. At coarse resolution numerical effects dominate, whereas at increasing ...
