Particle number, particle mass and NOx emission factors at a highway and an urban street in Copenhagen
Particle number particle mass NOx emission factors an urban street Copenhagen
2010/8/12
This paper presents measurements of traffic-generated gas and particle pollution at two sites, one near a major highway and one near a busy urban street in Copenhagen, Denmark. Both sites were equippe...
Biomass burning aerosol emissions from vegetation fires: particle number and mass emission factors and size distributions
Biomass burning aerosol vegetation fires mass emission factors
2010/2/21
Aerosol emissions from vegetation fires have a large impact on air quality and climate. In this study, we use published experimental data and different fitting procedures to derive dynamic particle nu...
Dispersion of traffic-related exhaust particles near the Berlin urban motorway – estimation of fleet emission factors
traffic-related exhaust particles Berlin urban motorway fleet emission factors
2009/5/7
Atmospheric particle number size distributions of airborne particles (diameter range 10–500 nm) were collected over ten weeks at three sites in the vicinity of the A100 urban motorway in Berlin, Germa...
Aerosol and NOx emission factors and submicron particle number size distributions in two road tunnels with different traffic regimes
NOx emission factors submicron particle size distributions different traffic regimes
2009/1/9
Measurements of aerosol particle number size distributions (18–700 nm), mass concentrations (PM2.5 and PM10) and NOx were performed in the Plabutsch tunnel, Austria, and in the Kingsway tunnel, Unite...
Seasonal variability of monoterpene emission factors for a ponderosa pine plantation in California
Seasonal variability monoterpene emission factors ponderosa pine plantation California
2009/1/6
Monoterpene fluxes have been measured over an 11 month period from June 2003 to April 2004. During all seasons ambient air temperature was the environmental factor most closely related to the measured...
Atmospheric number size distributions of soot particles and estimation of emission factors
Atmospheric number size distributions soot particles emission factors
2009/1/5
Number fractions of externally mixed particles of four different sizes (30, 50, 80, and 150 nm in diameter) were measured using a Volatility Tandem DMA. The system was operated in a street canyon (Eis...
Groundwater N2O emission factors of nitrate-contaminated aquifers as derived from denitrification progress and N2O accumulation
Groundwater N2O emission factors nitrate-contaminated N2O accumulation
2010/1/18
We investigated the dynamics of denitrification and nitrous oxide (N2O) accumulation in 4 nitrate (NO−3) contaminated denitrifying sand and gravel aquifers of northern Germany (Fuhrberg, Sulinge...
