Multiple same-level and telescoping nesting in GFDL's dynamical core (Grids, ICs)

Grids and ICs of the Geoscientific Model Development technical paper: Multiple same-level and telescoping nesting in GFDL's dynamical core. This paper studies the landfall of hurricane Laura (2020) and an Atmospheric river hitting California (2021) using global and regional domains with multiple same level and telescoping nested grids. Files are for the cases shown in this study: 1- Global C48 + nests 2- Global C768 + nests 3- Regional R192 + nests
