This work documents version two of the Department of Energy's Energy Exascale Earth
System Model (E3SM). E3SMv2 is a significant evolution from its predecessor E3SMv1 …

A latitude–longitude grid is used by almost all operational atmospheric forecast models, and
many research models. However, it is expected that the advantages of a latitude–longitude …

This report presents the details of the governing equations, physical parameterizations, and
numerical algorithms defining the version of the NCAR Community Atmosphere Model …

We discuss and evaluate the representation of atmospheric chemistry in the global
Community Atmosphere Model (CAM) version 4, the atmospheric component of the …

The Community Atmosphere Model (CAM) version 5 includes a spectral element dynamical
core option from NCAR's High-Order Method Modeling Environment. It is a continuous …

This paper describes the first implementation of the Δx= 3.25 km version of the Energy
Exascale Earth System Model (E3SM) global atmosphere model and its behavior in a 40 …

We derive a formulation of the spectral element method which is compatible on very general
unstructured three-dimensional grids. Here compatible means that the method retains …

For the first time a mesoscale‐resolving whole atmosphere general circulation model has
been developed, using the National Center for Atmospheric Research Whole Atmosphere …

We derive a formulation of the nonhydrostatic equations in spherical geometry with a Lorenz
staggered vertical discretization. The combination conserves a discrete energy in exact time …

We demonstrate that a small modification of the multiplicative, additive, and restricted
additive Schwarz preconditioner at the algebraic level, motivated by optimized Schwarz …
