Operational City Model ACCESS-C: aps1_access_c
The operational ACCESS-C is an operational NWP system with the highest resolution within weather bureau.
ACCESS-C has spatial resolution of 4km and vertical resolution of 70 levels. It runs out to 36 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.
Note: The naming convention of operational system is APSVERSION_MODEL
. Weather bureau regularly
upgrades the NWP system and names each version aps0, aps1 etc. aps1-access_c
is APS1 ACCESS-C NWP system.
ACCESS-C covers 6 domains, BN, SY, VT, AD, PH, DN
, which represent main Australian cities, Brisbane,
Sydney, Melbourne-Hobart, Adelaide, Perth and Darwin. These domains are detailed in the following table,
