Abstract

During a three week sampling campaign carried out in the period of photochemical activity, particle size distribution in a Mediterranean forest located in the plateau of central Spain was measured using a laser spectrometer. Experimental results of the number of particles covering 9 intervals in the 0.1-1 //m dynamic range are presented. Using spectral analysis as a statistical technique, 24-h daily significant peaks were obtained for each size range. In order to interpret the meaning of the peaks, particle size, sulphur dioxide and sulphate daily patterns are compared. The results have revealed the strong influence of sulphur dioxide oxidation on sulphates over the daily patterns of the aerosol spectra covering the 0.15-1 //m range. 1 Introduction Among
