Iris uses matplotlib for graphics and cartopy (also from the Met Office) for mapping (replacing basemap).

Features

• Reads/writes netCDF, UM PP and GRIB files
• Reads UM fieldsfiles

Use on raijin

Iris 1.6 is installed on raijin under ~access/apps. To use it

module use ~access/modules
module load iris

Examples

Galley of example plots with links to scripts is here.

Issues

• cartopy dependencies make installation awkward
• Incomplete standard names and other metadata with fieldsfiles
• Inconsistent merging of fields into multidimensional variables

Comparison with cdat

Note this refers to cdat 5 rather than the new UV-CDAT which I haven't really tried yet.
