Besides, I practiced another way. First, I created the vietnam.pts file and ran ./create_region with the x5.6488066.grid.nc file in order to generate the vietnam.grid file. To test my domain, I used the regional_terrain.ncl script and the result was displayed in the attachment.
Next, I followed the 1.3 step in the online tutorial to begin processing of the static, terrestrial fields. My input file consists of the vietnam.static.nc file, the vietnam.graph.info file. In addition, my namelist.init_atmosphere file was edited like that:
Code:
&nhyd_model
config_init_case = 7
config_start_time = '2019-09-01_00:00:00'
config_stop_time = '2019-09-04_00:00:00'
config_theta_adv_order = 3
config_coef_3rd_order = 0.25
/
&dimensions
config_nvertlevels = 55
config_nsoillevels = 4
config_nfglevels = 38
config_nfgsoillevels = 4
/
&data_sources
config_geog_data_path = '/work/users/agpc/share/geog/'
config_met_prefix = 'CFSV2'
config_sfc_prefix = 'SST'
config_fg_interval = 21600
config_landuse_data = 'MODIFIED_IGBP_MODIS_NOAH'
config_topo_data = 'GMTED2010'
config_vegfrac_data = 'MODIS'
config_albedo_data = 'MODIS'
config_maxsnowalbedo_data = 'MODIS'
config_supersample_factor = 3
config_use_spechumd = false
/
&vertical_grid
config_ztop = 30000.0
config_nsmterrain = 1
config_smooth_surfaces = true
config_dzmin = 0.3
config_nsm = 30
config_tc_vertical_grid = true
config_blend_bdy_terrain = true
/
&interpolation_control
config_extrap_airtemp = 'linear'
/
&preproc_stages
config_static_interp = true
config_native_gwd_static = true
config_vertical_grid = false
config_met_interp = false
config_input_sst = false
config_frac_seaice = false
/
&io
config_pio_num_iotasks = 0
config_pio_stride = 1
/
&decomposition
config_block_decomp_file_prefix = 'vietnam.graph.info.part.'
/
and my streams.init_atmosphere also was edited like:
Code:
<streams>
<immutable_stream name="input"
type="input"
filename_template="vietnam.grid.nc"
input_interval="initial_only" />
<immutable_stream name="output"
type="output"
filename_template="vietnam.static.nc"
packages="initial_conds"
clobber_mode="overwrite"
output_interval="initial_only" />
<immutable_stream name="surface"
type="output"
filename_template="x1.163842.sfc_update.nc"
filename_interval="none"
packages="sfc_update"
output_interval="86400" />
<immutable_stream name="lbc"
type="output"
filename_template="lbc.$Y-$M-$D_$h.$m.$s.nc"
filename_interval="output_interval"
packages="lbcs"
output_interval="6:00:00" />
</streams>
The model ran successfully:
Code:
-----------------------------------------
Total log messages printed:
Output messages = 3621
Warning messages = 7
Error messages = 0
Critical error messages = 0
-----------------------------------------
Logging complete. Closing file at 2020/08/11 10:47:39
In the next step, I interpolated regional initial conditions with the CFSV2 data. The namelist file was set-up similarly with the send step except:
Code:
&preproc_stages
config_static_interp = false
config_native_gwd_static = false
config_vertical_grid = true
config_met_interp = true
config_input_sst = false
config_frac_seaice = true
and the streams.init file was like:
Code:
<immutable_stream name="input"
type="input"
filename_template="vietnam.static.nc"
input_interval="initial_only" />
<immutable_stream name="output"
type="output"
filename_template="vietnam.init.nc"
packages="initial_conds"
clobber_mode="overwrite"
output_interval="initial_only" />
After running, it worked.
Code:
-----------------------------------------
Total log messages printed:
Output messages = 230
Warning messages = 1
Error messages = 0
Critical error messages = 0
-----------------------------------------
Logging complete. Closing file at 2020/08/11 10:57:03
In the next step (LBCs), I modified the namelist.init_atmosphere file:
and the streams.init file was likely:
Code:
<immutable_stream name="input"
type="input"
filename_template="vietnam.init.nc"
input_interval="initial_only" />
<immutable_stream name="output"
type="output"
filename_template="foo.nc"
packages="initial_conds"
clobber_mode="append"
output_interval="initial_only" />
There were no errors reported at the end of the log.init_atmosphere.0000.out file:
Code:
-----------------------------------------
Total log messages printed:
Output messages = 2742
Warning messages = 0
Error messages = 0
Critical error messages = 0
-----------------------------------------
Finally, I ran a regional simulation followed by the 4.4 step in the online toturials, the details of the namelist and streams files were attached in the attachments.
My process is right, doestn't it?
Thank!
