Particle size laboratory-scale biomass fires fast response instruments
2010/9/14
Particle size distribution from biomass combustion is an important parameter as it affects air quality, climate modelling and health effects. To date, particle size distributions reported from prior s...
Use of a mobile laboratory to evaluate changes in on-road air pollutants during the Beijing 2008 Summer Olympics
on-road air pollutants Beijing 2008 Summer Olympics
2009/11/19
China implemented systematic air pollution control measures during the 2008 Beijing Summer Olympics and Paralympics to improve air quality. This study used a versatile mobile laboratory to conduct in ...
Modeling of secondary organic aerosol yields from laboratory chamber data
secondary organic aerosol yields laboratory chamber data
2009/8/18
Laboratory chamber data serve as the basis for constraining models of secondary organic aerosol (SOA) formation. Current models fall into three categories: empirical two-product (Odum), product-specif...
Laboratory studies of ice formation pathways from ammonium sulfate particles
ice formation pathways ammonium sulfate particles
2009/3/13
Cirrus clouds are composed of ice particles and their formation pathways have been studied extensively in the laboratory. The ability of ammonium sulfate particles to act as nuclei for cirrus clouds h...
Laboratory investigation of photochemical oxidation of organic aerosol from wood fires 1: measurement and simulation of organic aerosol evolution
photochemical oxidation organic aerosol wood fires organic aerosol evolution
2009/3/13
Experiments were conducted to investigate the effects of photo-oxidation on organic aerosol (OA) emissions from flaming and smoldering hard- and soft-wood fires under plume-like conditions. This was d...
Laboratory measurements of the optical properties of sea salt aerosol
Laboratory measurements optical properties sea salt aerosol
2009/3/12
The extinction spectra of laboratory generated sea salt aerosols have been measured from 1 μm to 20 μm using a Bruker 66v/S FTIR spectrometer. Concomitant measurements include temperature, pressure, r...
Comparison of emissions from on-road sources using a mobile laboratory under various driving and operational sampling modes
emissions on-road sources driving and operational sampling modes
2009/3/12
Mobile sources produce a significant fraction of the total anthropogenic emissions burden in large cities and have harmful effects on air quality at multiple spatial scales. Mobile emissions are intri...
Fine and ultrafine particles in the Zürich（Switzerland）area measured with a mobile laboratory：an assessment of the seasonal and regional variation throughout a year
Fine and ultrafine particles Zürich seasonal and regional variation
2009/3/11
On occasion of the project YOGAM (year of gas phase and aerosol measurements), the spatial and temporal variation of selected aerosol and gas phase parameters was assessed for the Zürich (Switzerland)...
Vehicle fleet emissions of black carbon, polycyclic aromatic hydrocarbons, and other pollutants measured by a mobile laboratory in Mexico City
Vehicle fleet emissions black carbon polycyclic aromatic hydrocarbons Mexico City
2009/2/19
Black carbon (BC) and polycyclic aromatic hydrocarbons (PAHs) are of concern due to their effects on climate and health. The main goal of this research is to provide the first estimate of emissions o...
