Earth’s atmosphere more chemically reactive in cold climates
Earth’s atmosphere chemically reactive cold climates
2017/7/20
Unseen in the air around us are tiny molecules that drive the chemical cocktail of our atmosphere. As plants, animals, volcanoes, wildfires and human activities spew particles into the atmosphere, som...
Reactive processing of formaldehyde and acetaldehyde in aqueous aerosol mimics: Surface tension depression and secondary organic products
Surface tension depression and secondary organic products aqueous aerosol mimics
2011/9/2
The reactive uptake of carbonyl-containing volatile organic compounds (cVOCs) by aqueous atmospheric aerosols is a likely source of particulate organic material. The aque ous-phase secondary organic p...
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...
Evidence of the impact of deep convection on reactive Volatile Organic Compounds in the upper tropical troposphere during the AMMA experiment in West Africa
deep convection reactive Volatile Organic Compounds the AMMA experiment West Africa
2010/11/29
A large dataset of reactive trace gases was collected for the first time over West Africa during the African Monsoon Multidisciplinary Analysis (AMMA) field experiment in August 2006. Volatile Organic...
Development and application of a reactive plume-in-grid model: evaluation over Greater Paris
a reactive plume-in-grid model Greater Paris
2010/10/11
Emissions from major point sources are badly represented by classical Eulerian models. An overestimation of the horizontal plume dilution, a bad representation of the vertical diffusion as well as an ...
Trans-Pacific transport of reactive nitrogen and ozone to Canada during spring
Trans-Pacific reactive nitrogen ozone Canada spring
2010/9/21
We interpret observations from the Intercontinental Chemical Transport Experiment, Phase B (INTEX-B) in spring 2006 using a global chemical transport model (GEOS-Chem) to evaluate sensitivities of the...
Historical (1850–2000) gridded anthropogenic and biomass burning emissions of reactive gases and aerosols: methodology and application
reactive gases and aerosols methodology application
2010/8/16
We present and discuss a new dataset of gridded emissions covering the historical period (1850–2000) in decadal increments at a horizontal resolution of 0.5° in latitude and longitude. The primary pur...
Measurement and modelling of tropospheric reactive halogen species over the tropical Atlantic Ocean
tropospheric reactive halogen species the tropical Atlantic Ocean
2010/8/13
Although tropospheric reactive halogen chemistry is well studied in coastal and polar environments, the presence of halogens over the open ocean environment has not been widely reported. The impacts o...
An investigation of the origins of reactive gaseous mercury in the Mediterranean marine boundary layer
reactive gaseous mercury the Mediterranean marine boundary layer
2010/8/12
Atmospheric mercury species concentrations were measured during two oceanographic cruise campaigns covering the Adriatic Sea, the first during the autumn in 2004 and the second in the summer of 2005. ...
