Abstract We numerically simulate the temporal evolutions of the densities of charged and neutral species in a plasma generated with repetitively pulsed discharge in atmospheric environment at 60km altitude. The particles are divided into three categories according to their temporal behaviour. All charged particles exhibit oscillations with the same frequency as the driven power. Densities of elements O, N and H increase in a long-time scale. Densities of O3 and NO increase firstly and then decrease at t=0.65s; in particular, they have very similar density evolution profiles to each other.
