Abstract |
Different methods for measuring the intensities of Aitken nuclei sources in the atmosphere are presented. They are based on data obtained from aircraft measurements. The intensity of a small source area, some sq km, is obtained by the vertical repartition of the concentrations in the plume; for larger source area, some 10,000 sq km, this intensity is determined from the variation with day time of the vertical profiles of the concentration. The accuracy of the different methods is discussed. |
