Particle size distributions from laboratory-scale biomass fires using fast response instruments
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...
On microphysical processes of noctilucent clouds (NLC): observations and modeling of mean and width of the particle size-distribution
noctilucent clouds the particle size-distribution
2010/8/16
Noctilucent clouds (NLC) in the polar summer mesopause region have been observed in Norway (69° N, 16° E) between 1998 and 2009 by 3-color lidar technique. Assuming a mono-modal Gaussian size distribu...
Vertically-resolved particle size distribution within and above the mixing layer over the Milan metropolitan area
Vertically-resolved particle size distribution the mixing layer
2010/8/12
Vertical aerosol profiles were directly measured over the city of Milan during three years (2005–2008) of field campaigns. An optical particle counter, a portable meteorological station and a miniatur...
New particle formation during a- and b-pinene oxidation by O3, OH and NO3, and the influence of water vapour: particle size distribution studies
a- and b-pinene oxidation O3 OH NO3 water vapour particle size distribution
2009/3/12
New particle formation during the oxidation of a- and b-pinene (C10H16) by ozone, OH and NO3 was studied by measuring the particle size distributions with a scanning mobility particle sizer (TSI 3936)...

Particle size distribution particle mass measurements Copenhagen area Southern Sweden
2009/2/20
Particle size distribution (size-range 3-900nm) and PM10 was measured simultaneously at an urban background station in Copenhagen, a near-city background and a rural location during a period in Septem...
Heterogeneous oxidation of saturated organic aerosols by hydroxyl radicals: uptake kinetics, condensed-phase products, and particle size change
Heterogeneous oxidation saturated organic aerosols hydroxyl radicals uptake kinetics
2008/12/17
The kinetics and reaction mechanism for the heterogeneous oxidation of saturated organic aerosols by gas-phase OH radicals were investigated under NOx-free conditions. The reaction of 150 nm diameter ...

2008/11/12
An optical particle counter (OPC) is used in conjunction with lidar measurements to examine the characteristics of the particle size distribution in cirrus cloud in the tropical tropopause layer (TTL)...
Influence of particle size and chemistry on the cloud nucleating properties of aerosols
chemistry cloud nucleating aerosols
2008/10/30
The ability of an aerosol particle to act as a cloud condensation nuclei (CCN) is a function of the size of the particle, its composition and mixing state, and the supersaturation of the cloud. In-sit...
