A simplified ion-aerosol model for balloon measurements of ion conductivity and aerosol concentration

A simplified ion-aerosol model scheme is used to predict the small ion depletion and the consequent changes in stratospheric conductivity for the conditions at Hyderabad (17.5-degrees-N, 78.6-degrees-E). The inputs to the model on ion production rate, ion-ion recombination coefficient and charged ion-aerosol recombination coefficient are obtained from parametrization formulae. The balloon experimental results on small ion conductivity and aerosol concentrations at Hyderabad are compared with the simplified model results.
