CONCENTRATION CHANGES OF MSA AND MAJOR IONS IN ARCTIC AEROSOLS DURING POLAR SUNRISE
Aerosol samples were collected at Alert, Canada during the polar sunrise period. Major soluble species and MSA were determined by an ion chromatograph. Correlation coefficients among the concentrations of Na^+, Mg^<2+>, K^+ and Cl^- are high. The ratios of Mg^<2+>/Na^+ in the winter samp...
