Eddy covariance VOC emission and deposition fluxes above grassland using PTR-TOF
VOC grassland PTR-TOF
2011/2/24
Eddy covariance (EC) is the preferable technique for flux measurements since it is the only direct flux determination method. It requires a continuum of high time resolution measurements (e.g. 5–20 Hz...

We compare Tropospheric Emission Spectrometer (TES) versions 3 and 4, V003 and V004, respectively, nadir-stare ozone profiles with ozonesonde profiles from the Arctic Intensive Ozonesonde Network Stud...
Aerosol exposure versus aerosol cooling of climate: what is the optimal emission reduction strategy for human health?
Aerosol exposure aerosol climate the optimal emission reduction strategy human health
2010/10/11
Particles, climate change, and health have thought-provoking interactions. Air pollution is one of the largest environmental problems concerning human health. On the other hand, aerosol particles can ...
Moisture effects on carbon and nitrogen emission from burning of wildland biomass
carbon and nitrogen emission wildland biomass
2010/8/16
Carbon (C) and nitrogen (N) released from biomass burning have multiple effects on the Earth's biogeochemical cycle, climate change, and ecosystem. These effects depend on the relative abundances of C...
Analysis of emission data from global commercial aviation: 2004 and 2006
emission data global commercial aviation 2004 and 2006
2010/8/16
The global commercial aircraft fleet in 2006 flew 31.26 million flights, burned 188.20 million metric tons of fuel, and covered 38.68 billion kilometers. This activity emitted substantial amounts of f...
Dicarboxylic acids, metals and isotopic compositions of C and N in atmospheric aerosols from inland China: implications for dust and coal burning emission and secondary aerosol formation
Dicarboxylic acids C N atmospheric aerosols inland China dust and coal burning emission secondary aerosol formation
2010/8/16
Dicarboxylic acids (C2–C10), metals, elemental carbon (EC), organic carbon (OC), and stable isotopic compositions of total carbon (TC) and total nitrogen (TN) were determined for PM10 samples collecte...

mercury dispersion local and regional emission sources rural Central Wisconsin
2010/8/13
Simultaneous real-time changes in mercury (Hg) speciation- reactive gaseous Hg (RGM), elemental Hg (Hg°), and fine particulate Hg (Hg-PM2.5), were determined from June to November, 2007, in ambient ai...
Ozone response to emission changes: a modeling study during the MCMA-2006/MILAGRO Campaign
Ozone response emission changes the MCMA-2006/MILAGRO Campaign
2010/8/12
The sensitivity of ozone production to precursor emissions was investigated under five different meteorological conditions in the Mexico City Metropolitan Area (MCMA) during the MCMA-2006/MILAGRO fiel...
Anthropogenic sources of mercury emissions have a significant impact on global pollution. Therefore, finding uncharacterised sources and assessing the emissions from these sources are important. Howev...
The global SF6 source inferred from long-term high precision atmospheric measurements and its comparison with emission inventories
the global SF6 source long-term high precision atmospheric measurements emission inventories
2010/8/12
Emissions of sulphur hexafluoride (SF6), one of the strongest greenhouse gases on a per molecule basis, are targeted to be collectively reduced under the Kyoto Protocol. Because of its long atmospheri...
Estimating mercury emission outflow from East Asia using CMAQ-Hg
