This poster presents the Sodankylä Ion Chemistry (SIC) model, which is presently being modified in order to model the chemical effects of transient luminous events (TLEs) and artificial ionospheric heating. Calculated effects of ionisation and electron temperature enhancements during short bursts are shown. Although further work is needed to incorporate reactions of excited molecules and effects of transport, the results indicate that TLEs can be an important local source of chemically and radiatively active species, such as NO and ozone.
