Operational City Model ACCESS-C: aps2_access_c
APS2 ACCESS-C has spatial resolution of 1.5km and vertical resolution of 70 levels. It runs out to 42 hours
and 4 times daily, 00Z, 06Z, 12Z and 18Z (UTC). ACCESS-C nests within ACCESS-R (Australia Regional model
with 12km spatial resolution) for the initial condition and lateral boundary condition.
