 The [Lat-Lon-Cap grid](http://www.geosci-model-dev.net/8/3071/2015/) (or LLC) is a global ocean model grid which is widely used in the [MITgcm user community](https://mitgcm.readthedocs.io/en/latest/). It has 5 uneven subdomains, variable grid spacing, and continents [(Forget et al 2015)](http://www.geosci-model-dev.net/8/3071/2015/). LLC90's resolution is one degree albeit with modications in the Arctic and along the Equator.
