Abstract:

The results of recent laboratory investigations indicate that attempts to use ionic mobilities for the identification of positive ions in the lower ionosphere must necessarily fail. A mobility determination requires ion- molecule collisions chemical reactions occurring during these collisions will cause each mobility spectrum to tend toward a continuum. Because these reactions do not change the total number density of ions, conductivity measurements can be made using an average mobility for ions in air.
