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...
Simplified representation of atmospheric aerosol size distributions using absolute principal component analysis
atmospheric aerosol size distributions principal component
2008/12/1
Principal component analysis provides a fast and robust method to reduce the data dimensionality of an aerosol size distribution data set. Here we describe a methodology for applying principal compone...
Application of absolute principal component analysis to size distribution data: identification of particle origins
size distribution identification particle origins
2008/12/1
Absolute principal component analysis can be applied, with suitable modifications, to atmospheric aerosol size distribution measurements. This method quickly and conveniently reduces the dimensionalit...
