2009/7/22
High levels of trace gas (O3 and CO) and aerosol (BC, fine and coarse particle volumes), as well as high scattering coefficient (σp) values, were recorded at the regional GAW-WMO station of Mt. Cimone...
Primary and secondary contributions to aerosol light scattering and absorption in Mexico City during the MILAGRO 2006 campaign
aerosol light scattering Mexico City MILAGRO 2006 campaign
2009/6/16
A photoacoustic spectrometer, a nephelometer, an aethalometer, and an aerosol mass spectrometer were used to measure at ground level real-time aerosol light absorption, scattering, and chemistry at an...
Technical Note: A diagnostic for ozone contributions of various NOx emissions in multi-decadal chemistry-climate model simulations
ozone contributions various NOx emissions multi-decadal chemistry-climate model
2009/2/26
Nitrogen oxide (NOx=NO+NO2) emissions from various sources contribute to the ozone budget. The identification of these contributions is important, e.g. for the assessment of emissions from traffic. Th...
