FV3: Finite-volume CUBED-SPHERE DYNAMICAL CORE

"FV3 has been chosen as the dynamical core for the Next Generation Global Prediction System project (NGGPS),
designed to upgrade the current operational Global Forecast System (GFS) to run as a unified,
fully-coupled system in NOAA's Environmental Modeling System infrastructure."
