For E3SM v1, there were 3 generations of ocean meshes. Each started with "o" (e.g. oEC60to30). The first generation didn't have a suffix and the second generation was not ever used in E3SM. The third generation ended up with the truly terrible suffix v3. Meshes that are no longer supported in E3SM are indicated with strikethrough.
Mesh names in E3SM v2 and later
...
We dropped the "o" prefix because these meshes are used for both ocean and sea-ice. We now always but put the finer resolution before the coarser, we use wISC (with ice-shelf cavities) rather than wLI (with lance ice), and we append both the E3SM version (e.g. E2) and a revision number (e.g. r2). The revision number may get updated for a variety of reasons: including or excluding ice-shelf cavities; changing bathymetry; changing the initial condition; changing the vertical grid; etc.
