How to run a demo experiment
- Install WRF4G :
$ wget -O- https://meteo.unican.es/work/WRF4G/install.sh | bash ========================== WRF4G installation script ========================== --> Downloading wrf4g_x86_64_versions from https://meteo.unican.es/work/WRF4G ... 2015-02-13 13:07:09 URL:https://meteo.unican.es/work/WRF4G/wrf4g_x86_64_versions [36/36] -> "wrf4g_x86_64_versions" [1] This script will install WRF4G version: 2.0.0 --> Downloading wrf4g-2.0.0-x86_64.tar.gz from https://meteo.unican.es/work/WRF4G ... 2015-02-13 13:07:09 URL:https://meteo.unican.es/work/WRF4G/wrf4g-2.0.0-x86_64.tar.gz [1486041/1486041] -> "wrf4g-2.0.0-x86_64.tar.gz" [1] --> Unpacking wrf4g-2.0.0-x86_64.tar.gz in directory /home/user ... ==================================== Installation of WRF4G 2.0.0 is done! ==================================== In order to work with WRF4G you have to enable its environment with the command: . /home/user/wrf4g/bin/wrf4g_init.sh You need to run the above command on every new shell you open before using WRF4G, but just once per session. [user@mycomputer~]$ . /home/user/wrf4g/bin/wrf4g_init.sh
- Start up WRF4G :
[user@mycomputer~]$ wrf4g start Starting DRM4G .... OK Starting WRF4G_DB (MySQL) ... OK
- Show information about all available resources and their host :
[user@mycomputer~]$ wrf4g resource list RESOURCE STATE localmachine enabled [user@mycomputer~]$ wrf4g host list HID ARCH JOBS(R/T) LRMS HOSTNAME 0 x86_64 0/0 fork localmachine [user@mycomputer~]$ wrf4g host list 0 HID ARCH JOBS(R/T) LRMS HOSTNAME 0 x86_64 0/0 fork localmachine QUEUENAME JOBS(R/T) WALLT CPUT MAXR MAXQ default 0/0 0 0 1 1
- Define an experiment called test from a template :
[user@mycomputer~]$ wrf4g exp test define --from-template=single
- Take a look at test experiment configuration :
[user@mycomputer~]$ cat test/experiment.wrf4g [DEFAULT] # Experiment configuration name = test # Simulation domain max_dom = 1 # Experiment time-specification # start_date | end_date | chunk_size_h date_time = 2011-08-28_12:00:00 | 2011-08-30_00:00:00 | 12 calendar = standard timestep_dxfactor = 6 # Running options np = 1 requirements = ARCH = "x86_64" clean_after_run = yes save_wps = no real_parallel = no wrf_parallel = yes # Input data domain_path = /home/user/WRF4G_2_0/repository/domains/Santander_50km # Vtables must exist as Vtable.[input_extdata] extdata_vtable = GFS extdata_path = /home/user/WRF4G_2_0/repository/input/NCEP/GFS # Seconds between global analysis input times extdata_interval = 21600 preprocessor = default # Output output_path = /home/user/test/output postprocessor = SFC wrfout_name_end_date = no # app app = wrf_all_in_one | bundle | /home/user/WRF4G_2_0/repository/apps/WRF/WRFbin-3.4.1_r2265_gfortran.tar.gz # WRF-namelist parameters. Override namelist.input variables here namelist_version = 3.4.1 namelist = spec_bdy_width | 10 spec_zone | 1 relax_zone | 9 feedback | 0 history_interval | 180 frames_per_outfile | 3 e_vert | 28 mp_physics | 4 radt | 15 ra_lw_physics | 3 ra_sw_physics | 3
- Create the test experiment on WRF4G :
[user@mycomputer~]$ wrf4g exp test create --dir test Checking the variables in experiment.wrf4g file Preparing namelist... ---> Realization test_20110828T120000 ---> Chunk 1 2011-08-28_12:00:00 2011-08-29_00:00:00 ---> Chunk 2 2011-08-29_00:00:00 2011-08-29_12:00:00 ---> Chunk 3 2011-08-29_12:00:00 2011-08-30_00:00:00
- Submit the experiment :
[user@mycomputer~]$ wrf4g exp test submit ---> Submitting Realization test_20110828T120000 ---> Submitting Chunk 1 2011-08-28_12:00:00 2011-08-29_00:00:00 ---> Submitting Chunk 2 2011-08-29_00:00:00 2011-08-29_12:00:00 ---> Submitting Chunk 3 2011-08-29_12:00:00 2011-08-30_00:00:00
- Check the evolution of the experiment :
