Alex Mahalov brought a challenging problem to the SERV team; the visualization of large, multi-channel, temporal, volumetric data. The data is generated using the Weather Research and Forecasting (WRF) program at the Fulton High Performance Computing Center. Typical data sets are 10-100 GB, which is much more than Decision Theater's visualization cluster has in system memory.

In order to put the data in context, HPC's visualization team has designed and implemented software capable of displaying the atmospheric data over the planet. The software leverages several existing open source toolkits (i.e., OpenSceneGraph, OSSIM, and Minerva) and manages memory usage in order to avoid overloading the available resources.
