The atmosphere component remains EAM. Major changes since version 1 include:
all column-physics parameterizations are computed on a separate grid that has approximately half the number of points of the dynamics grid
...
a new nonhydrostatic dynamical core (running in hydrostatic mode) with semi-Lagrangian tracer transport

updated from v1 to v2
...
a new convective trigger (dCAPE/ULL) based on the dynamic Convective Available Potential Energy (CAPE) (dCAPE) and the Unrestricted Launch Level (ULL) concepts is used in ZM
minimum cloud droplet number changed
gravity wave drag energy conservation fixed and new tunings used
dust emission size distribution changed to emit more coarse dust particles
