SST Update - Real and WRF

Run the model (real.exe & wrf.exe)

1. Ensure you are in the WRF/ directory. For this case we are going to run in the test/em_real/ directory.

cd test/em_real

2. Link in the met_em files created with metgrid.exe

ln -sf ../../../WPS/met_em.d01.2016-10* .

3. Edit namelist.input
    ADD the following parameters to the appropriate namelist sections.
    Note 1 : Set up the basic namelist variables the same as you did for the Single Domain Case.
    Note 2 : For detailed explanations of these variables, as well as suggestions for best practices, see the Best Practices WRF Namelist page, or Chapter 5 of the WRF User's Guide

&time_control
auxinput4_inname = "wrflowinp_d<domain>",
auxinput4_interval = 360,
io_form_auxinput4 = 2
 
&physics
sst_update = 1,

Note: Do not change the syntax "wrflowinp_d<domain>", to "wrflowinp_d01". The syntax should be left exactly as above. Input interval is in minutes.
 

4. Run real.exe (verify that the program runs correctly)
    Note: This will overwrite wrfinput_d01 and wrfbdy_d01 files you may have from previous runs,
    so save your old files somewhere else if you would like to keep them.
    Check that the following three files have been created

wrfinput_d01
wrfbdy_d01
wrflowinp_d01

    What is contained in these files?
 

5. Run wrf.exe (verify that the program runs correctly)
    Check that the output files have been created.
 

6. Quick check of the contents of the wrfout file:

a. Use the ncdump utility:
    ncdump -h wrfout_d01_2016-10-06_00:00:00
    ncdump -v Times wrfout_d01_2016-10-06_00:00:00 (to see which forecast times are in the file)
b. Use the ncview utility.

To check if SST is updated in the model, look at field TSK over water.

7. Use any of the supported graphical tools to display the model output.
