Abstract A physicochemical model of excited polar ionosphere has been presented. The model makes it possible to calculate vertical profiles of concentrations of the following excited and ionized constituents: $ O_{2} $+, $ N_{2} $+, $ O^{+} $(4S), $ O^{+} $(2D), $ O^{+} $(2P), O(1D), O(1S), N(4S), N(2D), N(2P), NO, $ NO^{+} $, $ N^{+} $, $ N_{2} $($ A^{3} $$ Σ_{u} $+), $ N_{2} $($ B^{3} $$ П_{g} $), $ N_{2} $($ W^{3} $$ Δ_{u} $), and $ N_{2} $(B′3$ Σ_{u} $-) and the electron concentration during electron precipitations. The energy spectrum of the electrons at the upper boundary of the ionosphere and concentrations of neutral constituents are the input parameters of the model. A model has been compiled based on available publications and includes 56 physicochemical reactions that influence concentrations of the aforementioned constituents in the polar ionosphere. The method of calculating vertical profiles of the excitation rates of atmospheric gases and proper allowance for the electron-vibrational kinetics in the processes of exciting the triplet states of $ N_{2} $ are specific features of the presented model. The ionospheric model has been approbated using the results of the coordinated rocket–satellite experiment. The agreement between the modeling results and experimental data best for the time being is achieved.
