Graduate fellowships are awarded on the basis of academic excellence, scientific potential, and compatibility of the students' interests with current HAO research pursuits. Students selected to participate in the program will conduct research with one of the scientists at HAO on a mutually agreeable theoretical or experimental project. If the student has attained the official status of a Ph.D. candidate, it is expected that the chosen project will constitute the doctoral dissertation. HAO Graduate Fellows also enjoy the use of a wide range of technical facilities in their thesis work. These include access to the HAO Unix computers, NCAR IBM computer system, and the HAO and NCAR libraries and data archives. HAO graduate fellows are eligible to participate in active theoretical and observational ventures, such as thermospheric general circulation modeling or the advanced Stokes polarimeter experiment, and may utilize the Mauna Loa observing station in Hawaii.
