Learning unit contents

PART 1 : Atmosphere of the Earth
Chapter I: Atmospheric structure

• Hydrostatic equilibrium
• Thermal structure
• Convection, radiation, conduction

• Solar radiation spectrum
• Variability of the Sun's emissions
• Radiative transfer equation and applications
• Energy balance and climate
• Greenhouse effect

• Photochemical action of radiation
• Photochemistry of the atmosphere

• Formation and structure
• Chemical composition
• Neutrality and electric field

Learning outcomes of the learning unit

This course is meant to provide students with basic concepts of atmospheric physiccs and space environment. The common thread of the course is the vertical thermal profile of Earth's atmosphere. At the end of the course, students should be able to explain the overal shape of this thermal profile and to link it with the chemical composition and the energy balance of the atmosphere. They will learn how atmosphere evolves in time and space.

At the end of the course, students will also have acquired the basics of Earth's magnetic environment, of the radiation belts and the cosmic rays (astroparticles), of solar activity and its impact on space environment. With this knowledge, it will be possible to understand and to take into account the constraints imparted by space environment on Earth orbit and interplanetary space missions, particularly at the level of the design of space instruments.

This course contributes to the learning outcomes I.1, II.1, III.3, IV.3, VI.1, VII.3 of the MSc in aerospace engineering.

Assessment methods and criteria

Exam(s) in session

Any session

- In-person

oral exam

- Remote

oral exam


Additional information:

The exams are mainly meant to test the ability of the students to understand the physics behind the equations.These exams also appraise the overall knowledge of the course and the ability to link the different chapters.
Oral exam on the different lessons (3 questions). A list of questions will be distributed before the exams.
In case of remote oral examination, use of MS Teams or Skype  (backup solution).

Work placement(s)

Organizational remarks

It is highly recommended to attend the face-to-face classes.
All movies available for download on Vimeo must be viewed.
