[Wrf-users] WRF namelist.input for nested domain - Times

[Maria Prodanova]

Dear all,

I have experience with MM5, but I am a new user of WRF. I use WRF 3.1.1 
and I would like to run CMAQ 4.6 with output of WRF.
I run tutorial case without problem.  I prepare my domains - 3 nested 
domains (81, 27, 9 km). I run WPS without error.
I run real.exe and wrf.exe. I attach my namelist.input. The first I run 
real.exe and wrf.exe with the error in my namelist.input, I wrote  
time_step = 60 instead of 486, in this run I used fdda. All was OK, but 
the calculation was very slowly. I wrote  the write value of  time_step 
= 486, but the wrf.exe was  killed. I took out fdda options. As I think 
now all finished successfully ( I attach rsl.error.0000).
But in the files wrfout_d0*  the times is not correct ( my  
history_interval = 60,  60,   60). The times are:
Times =
  "2010-01-11_00:00:00",
  "2010-01-11_01:04:48",
  "2010-01-11_02:01:30",
  "2010-01-11_03:06:18",
  "2010-01-11_04:03:00",
  "......................................,
  "2010-01-13_11:07:48",
  "2010-01-13_12:04:30" ;
You may see the header of the wrfout_d01 and Times in the attached file 
z_Times_1_n.

When I wrote  time_step = 60 all was OK:
2010-01-11_00:00:00",
  "2010-01-11_01:00:00",
  "2010-01-11_02:00:00",
  "2010-01-11_03:00:00",
  "2010-01-11_04:00:00",
  "......................................,
  "2010-01-13_11:00:00",
  "2010-01-13_12:04:00" ;

I expected to be the same because history_interval = 60,  60,   60, and 
it is important for CMAQ the output to be every hrs.

Where is my error? Any information regarding this subject is greatly 
appreciated.

Thank you.

Maria
