Base Mesh Tasks

The mesh/spherical/qu/base_mesh/XXXkm/task and mesh/spherical/icos/base_mesh/XXXkm/task tasks can be used to create spherical, uniform MPAS meshes at the given resolution that are either quasi-uniform (qu) or subdivided icosahedral (icos).

There are also two variable-resolution base meshes: rrs6to18km and so12to30km.

The RRS mesh has a resolution that ranges from 6 km at the poles to 18 km at the equator, approximately scaling with the Rossby radius.

The SO mesh has a quasi-uniform, 30 km background resolution that transitions to 12 km in a region surrounding the Southern Ocean. The boundary of the high-resolution region attempts to approximately follow dynamical contours in the ocean, since rapid changes in resolution have been shown to steer ocean currents along isocontours of resolution.
