Ion production by cosmic rays is an important aspect of studies related to middle atmospheric electrodynamics and global electrical circuits. Since observations on ion production rates by cosmic rays are few and particularly scarce over low latitude stations and theoretical computations incomplete and not matched to observational data, the available information on experimental data is synthesized. New computations for ion production rates due to primary cosmic ray spectra are carried out using Bethe-Bloch formula applicable above 30 km and due to secondary cosmic gamma-ray spectrum using simple Chapman's theory below 30 km. The experimental data and computed values are compared and model ion production rates over a few latitudes are presented. The range of variations in the model values of ion production rate and ion densities under different geophysical conditions including the effect of background aerosols are also discussed.
