access_re_access_x_vn7.8_1.5km_run - ACCESS-NRI/accessdev-Trac-archive GitHub Wiki
Please refer the wiki page
https://trac.nci.org.au/trac/access/wiki/aps1_access_c_run
on how to set the environment, do the installation (replace apc1_access_c
with
access_x_vn7.8_1.5km
).
Please go to the wiki page
https://trac.nci.org.au/trac/access/wiki/access_c_vn7.8_1.5km_run
and check the resources required for variable domains and sample plots for reference. Also go to
https://trac.nci.org.au/trac/access/wiki/access_c_vn7.8_1.5km_background
to check the sizes of the standard domains for comparison.
Specify Running Dates
The initial cycle time
and final cycle time
are specified in accessdev::$HOME/roses/access_x_vn7.8_1.5km/suite.rc
.
The default value of initial cycle time
and final cycle time
are both set at 2014011800
because the test case only does one run 20140118 00Z(UTC). Please update those two variables
for different test cases. initial cycle time
and final cycle time
do not need to be same but
final cycle time
should not be earlier than initial cycle time
.
Environment Setting
You may modify the settings by updating raijin:$HOME/roses/access_x_vn7.8_1.5km/bin/env.access_x_vn7.8_1.5km
.
Most of the system variables are defined in this file. A list of variables you may need to modify are
as follows,
EXPTID
: an ID for the experiment, defaultS
.DATADIR0
: path where all the forecast data goes.INITIAL_DIR
: path where the dump file is.PI_DIR
: path where the pi files are.INITIAL_DATA
: naming convention of the dump file.PIPRE
: pi files prefix.PI_DATA
: naming convention of pi files.PI_MAX
: the number of pi files.ARCV_CLEAN
: pp files to be removed from disk.ARCV_GRB
: pp files to be converted togrib
format.ARCV_NCDF
: pp files to be converted to netCDF format.LOG
: path to hold log files.LOG_TASKS
: path to the central log files.
You can also modify the location in which netCDF data is located. Go to
raijin:$HOME/roses/access_x_vn7.8_1.5km/beans/mars/um2nc
, and update the variable
NC_ARCV_DIR="/short/$PROJECT/$USER/ncdata/"
to a new place.
Set Up Random Domain
The advantage of ACCESS-X is to run forecast over any domain within ACCESS-R region.
To set up your own domain, please go to raijin:$HOME/roses/access_x_vn7.8_1.5km/
and
modify SW1
and/or SW2
. Those files look like,
# for ancil
LAT_START=-38.0
LAT_END=-30
LON_START=147
LON_END=155
DELTA=0.0135
You can specify the four variables LAT_START
, LAT_END
, LON_START
and LON_END
, then run the model.
DELTA
is not needed to be changed because the suite is only tested with 1.5km resolution.
