EAS-A610 Advanced Topics in Solid Earth Geophysics (3) Physics of the earth's interior; emphasis on current research problems.  Topics from seismology, geology, heat flow, geomagnetism, and tectonophysics. Offered occasionally.

EAS-A619 Advanced Seminar in Geophysics (2) In-depth analysis of topics for Ph.D. students. Offered occasionally.

EAS-A620 Advanced Geomagnetism (3) Prerequisite: EAS-A451.  Lecture course on spherical harmonic analysis of the main magnetic field of the earth and of transient magnetic variations.  Processes in the ionosphere relating to geomagnetism; topics in paleomagnetism and magnetohydrodynamics included. Offered occasionally.

EAS-A631 Advanced Seismology I (3) Prerequisite: EAS-A540.  The solution of the three-dimensional elastic wave equation in a whole sphere and plane layered halfspace will be developed using concepts of Green's functions, moment tensors, dislocation theory.  Cagniard-de Hoop and wave number integration techniques will be introduced as complementary methods of solving the wave equation. Offered every Fall semester.

EAS-A632 Advanced Seismology II (3) Prerequisite: EAS-A631.  Wave propagation in a spherical earth is the focus of this course.  Wave equation solutions using free oscillations, WKBJ ray theory and surface waves are developed.  Modern techniques for wave propagation in an earth with laterally varying media will be addressed.  Theory for the inversion of seismic observations, e.g. free oscillation frequencies, surface wave dispersion or body wave travel times, for earth structure will be developed.  Offered every Spring semester.

EAS-A636 Principles of Radiation Transfer II (3) Prerequisite: EAS-A 536. A systematic approach to radiative transfer in absorbing, Mie scattering and emitting atmospheres, bounded by a lower surface, with the goal of computing local radiative heating and cooling. Offered occasionally.

EAS-A648 General Circulation of the Atmosphere (3) The nature and theories of the atmospheric general circulation, the energy and momentum budget of the atmosphere and the numerical simulation of the atmospheric general circulation. Offered occasionally.

EAS-A659 Seminar in Numerical Methods of Atmospheric Sciences (3) Topics include the solution of linear algebraic systems, generalized Fourier Series methods of boundary-initial-value problems, finite difference solutions of partial differential equations and statistical techniques of geophysical data processing. Applications to problems of interest in the atmospheric sciences. Offered occasionally.

EAS-A680 Topics in Methodology of Atmospheric Science (3) A systematic discourse on the essential concepts of the scientific methods in meteorology. The function of data in research is stressed. Offered occasionally.
