Space-based Gravity and Magnetic Field Monitoring

What it is about

You will learn the fundamentals of potential field theory as well as the mathematical description of the Earth's gravity and magnetic field. You will also gain insights into the concepts, objectives and satellite designs of important missions for gravity and magnetic field measurement (e.g. CHAMP, GRACE, GOCE, ØRSTE D, SAC-C, SWARM) and you will be able to transfer measurements into modelling, interpretation and monitoring of the Earth system.

What you will be able to do

Understand the fundamentals of potential field theory
Master the mathematical description of Earth's gravity and magnetic field
Know the concepts and goals of satellite missions for gravity and magnetic field measurement
Understand the necessary satellite design for observing potential fields
Recognise the relationship between measured quantities and potential field parameters
Apply methods for interpretation and modelling of Earth's gravity and magnetic fields
Analyse results and place them in the context of global Earth system monitoring

Assessment

Oral examHomework submissionSchriftlicher Laborbericht

The examination consists of an oral exam (duration: 30 minutes). Content-wise, it is checked whether you master the main concepts of potential field theory and space-based observation of gravity and magnetic fields, can establish connections and apply methods for data processing and modelling, and can interpret results. The exercises constitute an intermediate assessment; they count as passed if at least 60% of the tasks are completed. If the exercise is passed, the final grade may be improved by 0.3 (up to a maximum grade of 1.0).
