Measurements of electron density behind a decelerating shock wave in air in a shock tube are presented. A model is proposed that accounts for the effects of shock wave deceleration and boundary layer mass loss on shocked gas properties in a self-consistent manner. Calculated values of electron density based on this model are within a factor of 2 of measured values. Consequences of the combined effects of shock deceleration and boundary layer mass loss are seen to be of great importance for shock tube studies involving the determination of chemical reaction rates.
