Abstract

Aitken nuclei and ozone concentrations were measured, in concert with meteorological variables, while flying beneath the core of a jet stream at the 400 mb level. Stratospheric air which subsided to the flight level was richer in ozone, but similar in particle concentration when compared with adjacent tropospheric air. Concurrent carbon tetrachloride measurements by E. Robinson showed the tropospheric air to be richer in CCL4.
