Students in our PhD program undertake research that pushes the boundaries of our sciences, whether it be the latest in computer modeling or discovering new phenomena in the field. The following Doctor of Philosophy (PhD) requirements are formulated within the framework of the Graduate College requirements as described in A Handbook for Graduate Students and Advisors. The requirements of the degree of Ph.D. in Atmospheric Sciences correspond to the general requirements of the Graduate College for the degree, with the additional requirements outlined below.
