Visualization of Output from Community Multiscale Air Quality Model

A visualization tool for EPA’s Community Multiscale Air Quality modeling system, VisCMAQ, which is developed in this study as an OpenGL based visualization tool that has the capability to render data on both regular and irregular grids. The goal of this project is to enhance the VisCTM model, which was created last summer with additional flexibilities such as reading from NetCDF files. Also, the ability to process multiple time steps for multiple species at the same time. VisCMAQ would be able to read, and visualize different types of data that is written in C Language. These enhancements will allow the new VisCMAQ to accept an incorporation of data sets for various spatial domains and sets of chemical species. At this process the Visualization of the output from Multi scale Air Quality (VisCMAQ) model will be created. This VisMAQ project will link VisCTM tools with the Environmental Protection Agency’s Community Multi-scale Air Quality (CMAQ) Model system; which will utilize VisCTM import files written by the IOAPI library that is built upon the NetCDF file format. Key terms: Visualization, Irregular grid, volume rendering, OPEN-GL, Vis5D, VisCTM, CMAQ. ________________________________________________________________________ ____ Presenter/Authors Biography Dr. Thomas Jyh-Cheng Liu is an Associate Professor in Computer Science of NJCU (New Jersey City University).
