 Abstract The three pillars of geodesy, i.e. the geometry, rotation and gravity field of the Earth contribute to Earth system monitoring and will be considered here. 1) Earth rotation: theory, estimation and interpretation; 2) Gravity field: satellite missions, theory, estimation and interpretation; 3) Geodynamics (geometry): plate tectonics, earthquake cycle, isostasy and uplift rates. Objective Understand the basics of Earth rotation and gravity field theory, with what type of methods they are determined and what they contribute to monitoring the Earth system. Get familiar with the major geodynamic processes within the crust and mantle and how they are being observed and monitored. Content Part 1: Earth rotation - Kinematics of a solid body - Dynamic Eulerian equations of Earth rotation - Kinematic Eulerian equations of Earth rotation - Free rotation of the flattened Earth - Influence of Sun and Moon, Precession, Nutation - Earth as an elastic body - Determination of Earth rotation parameters - Mass distribution and mass transport affecting Earth rotation Part 2: Gravity field - Satellite missions - Gravity field determination from satellite data - Geoid computation from terrestrial data - Combination of satellite and terrestrial gravity fields - Precision of geoid computations - Mass distribution and transport affecting the Earth gravity fieldPart 3: Geodynamics: - Plate tectonics theory: including ocean bottom floor magnetism Curie temperature, age of the ocean bottom floor - Notions on crust material (oceanic/continental) - Concepts of mantle plumes, mantle convection and mantle flow and evidences supporting them - Earthquake cycle: elastic rebound theory, strain and stress measurements and measurements in the field during inter-, co- and post-seismic periods - Isostasy and strength models - Surface uplift rate applied to continental crust, volcanism, eroded areas.
