+Model for Prediction Across Scales (MPAS) is one of the supported atmospheric dynamical cores in Community Atmosphere Model - System for Integrated Modeling of the Atmosphere (CAM-SIMA). CAM-SIMA is the next-generation atmospheric component of Community Earth System Model (CESM).
+
+This auto-generated documentation provides a developer's guide to the Fortran interface and subdriver of MPAS dynamical core.
