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...
The role of the particle size distribution in assessing aerosol composition effects on simulated droplet activation
the particle size distribution aerosol composition effects simulated droplet activation
2010/8/13
Variations in the chemical composition of atmospheric aerosols alter their hygroscopicity and can lead to changes in the cloud-active fraction of the aerosols, or cloud condensation nuclei (CCN) numbe...
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...

An advanced particle microphysics model with a number of computationally efficient schemes has been incorporated into a global chemistry transport model (GEOS-Chem) to simulate particle number size di...
Long term particle size distribution measurements at Mount Waliguan, a high-altitude site in inland China
Mount Waliguan high-altitude site inland China
2009/8/7
Particle number size distributions in size range 12–570 nm were measured continuously at Mount Waliguan, a remote mountain-top station in inland China. The station is located at the altitude of 3816 m...
Classifying previously undefined days from eleven years of aerosol-particle-size distribution data from the SMEAR II station, Hyytiälä, Finland
aerosol-particle-size distribution SMEAR II station Hyytiä lä Finland
2009/3/12
Studies of secondary aerosol-particle formation depend on identifying days in which new particle formation occurs and, by comparing them to days with no signs of particle formation, identifying the co...
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...
Correlation between traffic density and particle size distribution in a street canyon and the dependence on wind direction
traffic density particle size distribution street canyon wind direction
2009/1/15
Combustion of fossil fuel in gasoline and diesel powered vehicles is a major source of aerosol particles in a city. In a street canyon, the number concentration of particles smaller than 300 nm in di...
Statistical estimation of stratospheric particle size distribution by combining optical modelling and lidar scattering measurements
stratospheric particle optical modelling lidar scattering
2008/11/19
A method for estimating the stratospheric particle size distribution from multiwavelength lidar measurements is presented. It is based on matching measured and model-simulated backscatter coefficients...
