<h1>MPAS-Atmosphere Meshes</h1>

<p class="noind">
Several resolutions of quasi-uniform and refined meshes are
available for download. Each download provides an SCVT mesh on the unit
sphere, the mesh connectivity (graph.info) file for the mesh, and
partitionings of the mesh (e.g., graph.info.part.32) for various MPI
task counts.

Additionally, for quasi-uniform meshes, "static" files using the default
datasets are available. The static file downloads provide single-precision
static files in
<a href="https://docs.unidata.ucar.edu/nug/current/netcdf_introduction.html#netcdf_64bit_data_format" target="_blank"> CDF-5/64-bit data format</a> and mesh connectivity files.

<h2>Creating limited-area subsets of meshes</h2>

<p class="noind">
MPAS-Atmosphere includes the capability to perform regional simulations.
Regional meshes are formed as subsets of existing meshes.
Currently, the <a href="https://github.com/MPAS-Dev/MPAS-Limited-Area" target="_blank">MPAS-Limited-Area</a>
Python tool is the supported method for generating regional meshes as subsets of any of the meshes
available on this download page. Please refer to the documentation provided with MPAS-Limited-Area
for details of its use.
