Processing DYNAMICO output

DYNAMICO outputs data on the native icasohedral grid in NetCDF-CF format, one file per field. Most fields are associated to hexagons, but some are associated to triangles. Native files can be visualized with the VTKMapper tool developed by Patrick Brockmann. Recently ParaView? has become able to visualize NetCDF-CF files too. For quantitative post-processing it is probably best to interpolate to Cartesian curvilinear coordinates such as lat-lon.

Visualization with Paraview

Paraview requires some data and metadata that are not currently provided in the NetCDF output. Yann has done the required modifications and will commit them soon.

Interpolation to lat-lon with cdo

​cdo can interpolate from unstructured meshes to lat-lon grids. However it also needs in a single file data and metadata that are current split in separate files. The following commands will merge the necessary data in a single file that can be processed by cdo.
