Space Weather: Environmental Impact Assessment

The purpose of studying the discipline: to give students a modern picture of knowledge about the Sun and solar activity, about the impact of energetic particles (of solar and cosmic origin) on processes in the Earth's atmosphere. Separately, paying attention to the risks associated with extreme events on the Sun and in outer space on the state of the ozone layer and surface temperature, assessing the degree of danger to the environment.

The course will introduce students to various sources and energies of particles that precipitate into the Earth's atmosphere; processes of atmosphere ionization by protons of galactic cosmic rays, solar energy particles, high-energy and relativistic electrons; consideration of the mechanisms of the impact of energetic particles on the Earth's atmosphere, including chemical changes in the upper and middle layers of the polar atmosphere, dynamic and radiation processes in the Earth's atmosphere, as well as the formation of the Earth's climate.

The acquired knowledge and skills will allow students to independently determine the level of danger during extreme solar events and geomagnetic storms, inversions and excursions of the geomagnetic field, assess these threats and assess the degree of danger to the environment and society.

The form of education is online. Weekly classes will include watching thematic video lectures, studying additional materials and completing tests with automated verification of results. All assignments must be completed to obtain a certificate.

No prior experience required.

Module 1. Sun and solar system, solar activity, galactic and solar cosmic rays, Earth's magnetosphere, geomagnetic storms and substorms, auroral and relativistic electrons.

Module 2. Energetic particles and their impact on the environment and the Earth's atmosphere. Characteristics of interplanetary space associated with precipitation of protons and electrons. Registration of energetic particles: ground-based measurements, balloon measurements, satellite measurements.
