Paper Description
This course provides an introduction to the physics of the Earth's atmosphere, our space environment, and the Sun. Starting from the Sun we will trace the paths taken by solar photons, protons and electrons through the solar system, the Earth's magnetic field, ionosphere, finally reaching the atmosphere.
Prerequisites:
PHSI 332
This paper consists of 15 lectures and 3 tutorials. There are 3 assignments.
Assesment:
Final Exam 70%, Assignments 30%

The overall goal of this course is to provide each student with solid understanding of principles of the Sun-Earth system and how different parts of this highly dynamic system are connected via physics.
By the end of the course you are expected to have gained understanding of the following
- Principles of plasma physics as applied to space physics
- Properties of space plasmas, including quasi neutrality
- Mechanisms and equations controlling the motion of particles in a non-uniform magnetic field
- Electrical conductivity and current systems in the Earth's ionosphere
- Structure of the neutral atmosphere
- Derivation of hydrostatic equations for the neutral atmosphere
- Familiarity of various observation techniques used to monitor solar activity, geospace and the atmosphere
- How to use observations and geospace simulations to track propagation and impact of solar storms throughout the Sun-Earth system
Topics:
- Introduction to the Sun-Earth system
- The Sun: structure from core to corona, origins of solar magnetic field, solar activity
- Solar magnetic field and its expansion to space: The Interplanetary magnetic field, solar wind
- Earth's magnetic field: From dipole to interaction with solar wind
- Outer and inner magnetosphere
- Currents and plasma in the magnetic field, radiation belts
- Movement of particles in the magnetic field, bounce and drift
- Interaction with solar activity, storms in the magnetosphere, acceleration and loss of particles, waves in plasma
- Ionosphere: formation and layers, electric fields, conductivity and currents, aurora
- Neutral atmosphere: Structure, composition, dynamics and circulation, interaction of the neutral atmosphere with solar activity and the magnetosphere
