We propose to implement and test a new cubed-sphere finite-volume, non-hydrostatic dynamical core developed at NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL) for use in future GMAO atmospheric general circulation models. The core will be implemented under the MAPL software interface to the Earth System Modeling Framework (ESMF) used in GMAO systems. It will be tested at various resolutions in climate, numerical weather prediction (NWP), and data assimilation modes. We will evaluate the core’s hydrostatic and non-hydrostatic options at resolutions from 15 to 50 km, and will compare the resulting non-hydrostatic implementations at the two centers using resolutions as close to cloud-resolving as computing resources will allow (~5km). For the GMAO, this proposal prepares the pathway to the next generation GEOS-6 system. For GFDL it will provide additional resources for a more thorough evaluation of the core and particularly of its performance at very high resolution in a numerical weather prediction (NWP) setting using the GMAO’s atmospheric data assimilation system. The non-hydrostatic finite volume dynamical core is already undergoing advanced testing at GFDL and a hydrostatic version using the same code base is being tested at GMAO. This collaboration between GMAO and GFDL will further the interests of both parties in the development advanced climate and NWP models, and represents a key step in ensuring NASA’s ability to continue to analyze and assimilate high-resolution satellite data using state-of-the-art models.
