How do you know if AOSC is a good fit for you?

The AOSC department consistently ranks among the top atmospheric and oceanic sciences departments in the US, and our students further benefit from our unique location in the Washington D.C. area, where we foster close connections with NOAA, NASA, and other earth-science institutes. To help applicants learn more about the department, the AOSC admissions committee is hosting a virtual admissions “open house” series this fall. Each open house will include an introduction by select faculty members and graduate students and an open forum for discussing the AOSC program. These events are also a great opportunity to learn more about the admissions process and life in the DC area. 
All prospective students are welcome to attend these events. If interested, please send an email to Jonathan Poterjoy ( with the subject line “Admissions Open House.” In the main body of the email, be sure to mention one or more dates that you would like to participate in these events.


A recommended undergraduate background includes calculus, differential equations, linear algebra, calculus-based physics, and general chemistry.

All students must have an undergraduate degree from an accredited college or university in the US or an equivalent degree attained in a foreign country. A GPA of 3.0 (out of 4.0) is typically required.

The GRE is not required to apply for the Master of Professional Studies program in Atmospheric and Oceanic Science.
