Carbonaceous and Ionic Components of Atmospheric Fine Particles in Beijing and Their Impact on Atmospheric Visibility
PM2.5 OC EC Ion Visibility
2016/3/25
Ground-based observation of fine particulate matter (PM2.5) in Beijing was carried out continuously in 2006. The
carbonaceous and ionic components, as well as their distribution characteristics and s...
Major components of atmospheric organic aerosol in southern California as determined by hourly measurements of source marker compounds
atmospheric organic aerosol southern California source marker compounds
2010/12/28
We report the first hourly in-situ measurements of speciated organic aerosol (OA) composition in an urban environment. Field measurements were made in southern California at the University of Californ...

In this study we compile and present results from the factor analysis of 43 Aerosol Mass Spectrometer (AMS) datasets (27 of the datasets are reanalyzed in this work). The components from all sites, wh...
Discriminating low frequency components from long range persistent fluctuations in daily atmospheric temperature variability
long range persistent fluctuations daily atmospheric temperature low frequency components
2009/7/22
This study originated from recent results reported in literature, which support the existence of long-range (power-law) persistence in atmospheric temperature fluctuations on monthly and inter-annual ...
Spatio-temporal variability and principal components of the particle number size distribution in an urban atmosphere
Spatio-temporal variability particle number size distribution urban atmosphere
2009/5/15
A correct description of fine (diameter <1 μm) and ultrafine (<0.1 μm) aerosol particles in urban areas is of interest for particle exposure assessment but also basic atmospheric research. We examined...
