ATMOSPHERIC SCIENCES 749, RADIATION TRANSFER

PROJECT

Project: The project will be an application of radiation transfer to a problem of interest to you. The project will be a combination of library research and of numerical simulation. Due date for title and abstract is March 17, an outline is due April 7, and the finished paper is due May 2nd. DRI has a well-equipped Atmospheric Science library. Use the expected writing style for Journal of the Atmospheric Sciences in preparing the final paper. See also Uncover, a web server for references.

Philosophy: Use theory and computations to obtain a solution for a problem in radiation transfer. Then follow through with a discussion of the results. It is generally best to choose a problem that you completely understand and can thoroughly analyze rather than choosing an extremely complex problem that requires use of numerical code that produces output hard to digest. Use this opportunity to learn something of interest to you. It is certainly ok that the topic you choose relates to your research at DRI.

Ideas for project topics. You are free to make other choices as well. We need to agree on the suitability of your topic so as soon as you find one, let me know. See also related radiation transfer sites.
