Abstract
Energetic particle precipitation (EPP) can affect the chemical composition of the Earth’s atmosphere. Particles emitted by the Sun in the form of the solar wind (SW) reach the Earth’s magnetosphere, accelerate to high energies, and reach the dense layers of the atmosphere, triggering chains of chemical reactions that lead to a change in the chemical composition of the atmosphere, thereby EPP leads to ionization of the atmosphere.
In this paper, we considered the response of the atmosphere to energetic electron precipitation (EEP) in a high-latitude atmosphere above Apatity (67.57oN, 33.56oE, L = 5.3). We exploited two versions of a one-dimensional radiative-convective model of the atmosphere with interactive neutral and ionic chemistry. The first version calculates the production of primary radicals as a function of ionization rate and altitude; the second, introduced by us—additionally includes treatment of the complete ion chemistry. The models gave results which were compared in the paper.
