Última North Sea aerosol characterization by single particle analysis techniques OMA Van Malderen, H.; De Bock, L.A.; Injuk, J.; Xhoffer, C.; Van Grieken, R.. Tipo: Info:eu-repo/semantics/article Ano: 1993 URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=2794 Single particle analysis of aerosols, observed in the marine boundary layer during the Monterey Area Ship Tracks Experiment (MAST), with respect to cloud droplet formation OMA De Bock, L.A.; Joos, P.E.; Noone, K.J.; Pockalny, R.A.; Van Grieken, R.E.. The chemical composition of individual particles >0.2 µm sampled during the MAST-experiment were analysed by SEM-EDX, in combination with multivariate techniques. The objective of this experiment was to identify the mechanisms responsible for the modification of marine stratocumulus clouds by emissions from ships and in a wider sense to provide information on the global processes involved in atmospheric modification of cloud albedo. Aerosols were examined under different MBL pollution levels (clean, intermediately polluted and moderately polluted) in five different reservoirs: background below-cloud and above-cloud aerosol; background cloud droplet residual particles; below-cloud ship plume aerosol and ship track cloud droplet residual particles.

Ano: 2000 URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=8877 Individual aerosol particle composition variations in air masses crossing the North Sea OMA De Bock, L.A.; Van Malderen, H.; Van Grieken, R.. Single-particle analysis on North Sea and rainwater samples was performed by electron-probe X-ray microanalysis (EPXMA). The analysis was mainly focused on the determination of the inorganic composition of giant particles with diameters above 1 µm. Multivariate techniques were used for the reduction of the data set and for source apportion. Based on the relative abundances found by hierarchical cluster analyses according to the Ward error sum method, three to eight different aerosol types were distinguished. Crossing the North Sea, the changes in air mass composition appeared as a decrease in the abundance for the aluminosilicate particles and relative increase for NaCl and seawater crystallization products. Principal factor analysis revealed four...
