Mosaics are assemblies of block-structured grids that share properties with both structured and unstructured grids. An example is the cubed-sphere grid used by some atmospheric models, which avoids the grid singularities of longitude-latitude grids at the poles. A special feature of mosaics is that the connectivity information between the block-structured grid patches (tiles) must be provided in order for applications to be able to access neighboring vertex/cell data, and in order to correctly visualize cell centered data. It is shown through specific examples how the Climate Data Analysis Tools (CDAT) can be used to load mosaic data and visualize fields across the multiple tiles of the cubed-sphere and tripolar grids.
