Abstract:

The goal is to develop a Unified Air-Sea Visualization System UASVS to enable the rapid fusion of observational, archival, and model data for verification and analysis. To design and develop UASVS, modelers were polled to determine the gridding structures and visualization systems used, and their needs with respect to visual analysis. A basic UASVS requirement is to allow a modeler to explore multiple data sets within a single environment, or to interpolate multiple datasets onto one unified grid. From this survey, the UASVS should be able to visualize 3D scalarvector fields render isosurfaces visualize arbitrary slices of the 3D data visualize data defined on spectral element grids with the minimum number of interpolation stages render contours produce 3D vector plots and streamlines provide unified visualization of satellite images, observations and model output overlays display the visualization on a projection of the users choice implement functions so the user can derive diagnostic values animate the data to see the time-evolution animate ocean and atmosphere at different rates store the record of cursor movement, smooth the path, and animate a window around the moving path repeatedly start and stop the visual time-stepping generate VHS tape animations work on a variety of workstations and allow visualization across clusters of workstations and scalable high performance computer systems.
