JEDI-MPAS

Jedi-mpas 1.0.0

JEDI-MPAS is a multi-component software package that provides everything that is needed to run data assimilation applications for the atmospheric core of the Model for Prediction Across Scales (MPAS).  The National Center for Atmospheric Research (NCAR) and the JEDI core team jointly develop JEDI-MPAS.

MPAS is a collaborative project for developing atmosphere, ocean and other earth-system simulation components for use in climate, regional climate and weather studies, whose primary development partners are Los Alamos National Laboratory and NCAR. The atmospheric core of MPAS solves the the fully compressible nonhydrostatic equations of fluid motion on an MPAS unstructured Voronoi mesh and offers a subset of the Advanced Research WRF physical parameterizations.  MPAS is used at NCAR for research into Earth-System predictability, spanning both weather and climate.

JEDI-MPAS employs MPAS’s native meshes, including regional and variable-resolution meshes, and performs I/O with native MPAS-A files.
