Editing WRF restart variables

[Dr_MRW]

Hello WRF forum,

I am attempting to run WRF Real past spin up time, and then perturb the temperature and pressure fields in a restart file. However I seem to be missing something, because when I restart WRF the edited and perturbed WRF variables disappear. They seem "not to stick." See this related post describing similar issues.


I have tried both the NCAR tool for changing WRF netCDF files along with a python script IU wrote. Neither seems to work.

I'm sure other have done something similar and got this to work.

Thank you in advance,
-Matt W.

Matt,

What variables did you modify and how? Thanks.

Hi Ming,

the WRF restart file has limited variables compared to a wrfout file, so I am uncertain if i am approaching this correctly. Untimely i am trying to add a perturbation bubble for the potential temperature in a restart file.

So far I tried T, THM_1, THM_2, T_PHYS, and various combinations with no luck.

Any suggestions?

Thank you so much!

THM_1 and THM_2 would be the variables that you should change. Note that they are moist potential temperature and include a qv term.
THM_1 is used at the beginning of the time-step, but I suppose it is safer to change both the same way.

Please try and let me know how it works. Thanks.

That did the trick! thank you so much Ming!
