The Nonhydrostatic Icosahedral Model, NIM, is a new grid mesh global weather model still in its final stages of development. I have developed the beginning documentation which involved working closely with Dr. MacDonald to clean up and add comments within the NIM Fortran code; create a public website, user guide, and modeler’s guide; develop figures to illustrate the fundamentals of the model; learn to run the model; collaborate with the model’s developers and team to innovate new documentation methods. In order to successfully document and publicize the model, I developed a strong foundation in the comprehension of the model itself, including the code/variables/routines. This required understanding the fundamental NIM equations, their representation in finite volume form and analytical methods used to solve them, and the type of computational and parallelization methods used within the model. NIM has been successfully documented so that the entire community, and in particular modelers, users, and the public, can clearly understand and use the model as well as benefit from the model’s forecasts and research advances.
