Abstract: Aerosol number concentrations were measured, using a photoelectric nucleus counter, at three locations in Antarctica. This nucleus counter was of high sensitivity and equipped with a diffusion battery to permit estimation of particle size. Concentrations of 50 to 100 cm?3 were predominant at the South Pole; concentrations of 100 to 150 cm?3 were most common at Siple Station (78°S, 84°W) where some maritime influence might be present. At both of these stations, concentrations of 500 to 1200 cm?3 very small particles were detected when the polar tropopause lowered. Concentrations of 50 to 150 cm?3 were found at Ross Island with continental winds; concentrations of 300 cm?3 accompanied maritime winds.
