Due to the quickly growing size of the simulation data, analysis and visualization of the time-dependent multivariate 3D results is an increasingly difficult task. Visual data analysis is a powerful tool to handle the challenges of these large datasets, with focus particularly on the major patterns and processes simulated by the complex coupled models. For interactive 3D visualization of climate data, DKRZ offers its users access to an advanced visualization server system (based on HP's SVA architecture) and a remote 3D-rendering solution (HP RGS), which allows interactive use of the system from remote locations. The visualization solution mainly used is
, as it provides unique visualization capabilities.
With its powerful NetCDF-CF1 file interface, Avizo software is able to read and visualize the typical long time series of multivariate 3D data produced by weather and climate models using the most common native file formats. Depending on the local hardware configuration, large files can be cached in memory in order to accelerate the interactive access. Very large time-dependent files can be visualized right away from the hard disks.
