How to prescribe tsk in wrf-les ideal case?

Hi,
I'm running ideal wrf-les and want to prescribe tsk distribution.(What I have modified is all in module_initialize_ideal.F, I noted wangx where I modified for quick search) I found that in wrfout results, the initial tsk is 320K(I modified), but as the mode starts to integrate, at the first moment, the tsk is 302K.
I have looked through all similar posts and still have no idea about this.I'd appreciate it if you could give me some advice.

For WRF-LES, tsk is initialized based on theta_surf, which is read from the input sounding.

Please see the code in module_initialize_ideal.F:
Code:
1638   CASE(les)


1639   DO J = jts, min(jde-1,jte) 


1640   DO I = its, min(ide-1,ite)


1641          grid%tsk(i,j) = theta_surf * (p_surf/p1000mb)**rcp


1642          grid%tmn(i,j) = grid%tsk(i,j)-0.5


1643   ENDDO


1644   ENDDO
