Research City Model access_c_vn7.8_1.5km

The standard experiment access_c_vn7.8_1.5km is a research city model developed

in ESM program of CAWCR. Compared with the operational aps1-access_c, it has higher

spatial resolution of 1.5km but still keeps the vertical resolution of 70 levels.

The UM version of access_c_vn7.8_1.5km is upgraded to 7.8 instead of 7.6 in aps1-access_c.

access_c_vn7.8_1.5km runs out to 36 hours and twice daily, 00Z and 12Z (UTC) experimentally.

access_c_vn7.8_1.5km also nests within ACCESS-R.

Note: The naming convention of research system will follow MODEL_UMVERSION_RESOLUTION. In

this case, MODEL is access_c, UMVERSION is vn7.8 and spatial resolution is 1.5km, so the

standard experiment is named as access_c_vn7.8_1.5km.

Same as the aps1_access_c, access_c_vn7.8_1.5km also 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,

City	Domain	Lat. Range	Lon. Range	Grids	Res.	fcst_hrs	MARS	opendap
`Brisbane`	`BN`	-31.0S, -22.0S	148.00E, 156.0E	668X594	1.5km	36	akxb	bdmb
`Sydney`	`SY`	-38.0S, -30.0S	147.00E, 155.0E	594X594	1.5km	36	akxs	bdms
`VicTas`	`VT`	-46.0S, -33.0S	139.00E, 151.0E	964X890	1.5km	36	akxv	bdmv
`Adelaide`	`AD`	-39.5S, -29.5S	132.00E, 142.0E	742X742	1.5km	36	akxa	bdma
`Perth`	`PH`	-37.0S, -28.0S	112.00E, 123.0E	668X816	1.5km	36	akxp	bdmp
`Darwin`	`DN`	-16.0S, -8.0S	128.50E, 140.0E	594X852	1.5km	36	akxd	bdmd

The forecast data is available on MARS from 2013-10-23 to 2014-03-31. The data is available on opendap of

raijin:/g/data/rr4/opendap_esm/access-ff from 2014-03-18. Please see the table above for the MARS/opendap ID

for each domain. (few missing for both datasets due to system faults).

The experimental suite running on raijin may be switched off anytime without further notice.

Please check the wiki for updates.
