The change in spectra of mobility of small atmospheric ions during molecular diffusion and convection in air has been studied experimentally. There occurs no change in mobility spectra for the molecular diffusion in windless air because both coefficients of adhesion and diffusion are proportional to the mobility. On the other hand, the mobility spectrum of ions changes during the convections due to the inverse proportionality of the lifetime to the mobility of ions. The mean lifetime of ions was experimentally obtained from the measured concentration distribution of ions in a round free jet. The results showed that the mobility spectrum of ions changes with increasing downstream distance due to a rapid dissipation of the ions of high mobility during the convections.
