[Wrf-users] How does WRF compute KTAU value

[Lyndon Mark Olaguera]

Hi WRF,

I'd like to ask a question about WRF FDDA.
i want to know how does WRF compute for the KTAU (formula for solving KTAU).
In my rsl.out.0000 file, the value of this is at an interval of 25. I will
attach it here.
I will also attach my namelist.input here

In wrf_fddaobs_in.F the KTAU is equal to grid%itimestep
what is the value of this itimestep?
and also what is the effect of the value of KTAU in the nudging run?

thanks.
