Spatial variability of POPs in European background air
Spatial variability POPs European background air
2011/2/25
Passive air samplers (PAS) were deployed at 86 European background sites during summer 2006 in order (i) to gain further insight into spatial patterns of persistent organic pollutants (POPs) in Europe...
Atmospheric deposition of mercury and major ions to the Pensacola (Florida) watershed: spatial, seasonal, and inter-annual variability
mercury major ions the Pensacola (Florida) watershed inter-annual variability
2010/8/13
Atmospheric deposition was measured at three sites in the Pensacola Bay watershed, Florida, between November 2004 and December 2007. Mercury deposition in the Pensacola Bay watershed was similar to th...
Airborne measurements of the spatial distribution of aerosol chemical composition across Europe and evolution of the organic fraction
Airborne measurements aerosol chemical composition Europe the organic fraction
2010/8/12
The spatial distribution of aerosol chemical composition and the evolution of the Organic Aerosol (OA) fraction is investigated based upon airborne measurements of aerosol chemical composition in the ...
Tempo-spatial variation of emission inventories of speciated volatile organic compounds from on-road vehicles in China
Tempo-spatial variation speciated volatile organic compounds on-road vehicles China
2009/9/23
Emission inventories of sixty-seven speciated non-methane volatile organic compounds (NMVOC) from on-road vehicles in China were estimated for the period of 1980–2005, using seven NMVOC emission profi...
Time span and spatial scale of regional new particle formation events over Finland and Southern Sweden
regional new particle formation events Finland Southern Sweden
2009/7/23
We investigated the time span and spatial scale of regional new particle formation (NPF) events in Finland and Southern Sweden using measured particle number size distributions at five background stat...
Spatial and temporal UV irradiance and aerosol variability within the area of an OMI satellite pixel
UV irradiance OMI satellite pixel aerosol variability
2009/7/22
Results of an experimental campaign that took place in the greater Thessaloniki area were used to investigate temporal and spatial UV variability within an OMI satellite pixel. UV irradiance and aeros...
Temporal and spatial variability of glyoxal as observed from space
biogenic processes VOC glyoxal
2009/7/15
Glyoxal, CHO.CHO, is produced during the oxidation of volatile organic compounds, VOC, released by anthropogenic activities, biogenic processes and biomass burning. It has a short chemical lifetime of...
Intra-community spatial variability of particulate matter size distributions in Southern California/Los Angeles
Intra-community spatial variability particulate matter size distributions Southern California/Los Angeles
2009/3/13
Ultrafine particle (UFP) number concentrations vary significantly on small spatial and temporal scales due to their short atmospheric lifetimes and multiplicity of sources. To determine UFP exposure g...
Spatial distribution of Δ14CO2 across Eurasia: measurements from the TROICA-8 expedition
Spatial distribution Eurasia TROICA-8 expedition
2009/3/12
Because fossil fuel derived CO2 is the only source of atmospheric CO2 that is devoid of 14C, atmospheric measurements of Δ14CO2 can be used to constrain fossil fuel emission estimates at local and reg...
