Dear WRF experts:

I encountered the following warning when running wrf.

Code:

d01 2021-03-20_06:00:00 Input data processed for aux input  10 for domain   1

My input data file is GFS 25km available every 6-hours.
I am attaching my namelist.input here.

Although the run successfully finished, I want to get rid of this warning.
Will this also affect the results?

Any suggestions on how to solve this issue??


I'll appreciate any help on this matter.

Hi,
Can you issue the following:
Code: 
ncdump -v Times wrffdda_d01 >& fdda.log
and attach that fdda.log file? Thanks!
 
@Kwerner

Apologies.. I did not save the fdda file for this run.
Please see the attached fdda.log of our recent run. This error is still there.

When I ncdump the wrfout file it has 73 time steps while the fdda file has 72 only.


Here's the contents of the fdda.log

Thanks for sending that. Unfortunately I need to see the fdda.log file, along with the corresponding namelist.input file. Can you send the updated namelist.input that should be used with the wrffdda_d01 file? Can you also attach the full error log? Thanks!
 
Lyndz,
Thank you for sending those. It looks like when you created the wrffdda* file, it was set to hourly intervals. The times in that file are (for e.g.,)
Code: 
Times =
  "2021-03-22_06:00:00",
  "2021-03-22_07:00:00",
  "2021-03-22_08:00:00",
  "2021-03-22_09:00:00",
  "2021-03-22_10:00:00",
  "2021-03-22_11:00:00",
  "2021-03-22_12:00:00",
  "2021-03-22_13:00:00",
  "2021-03-22_14:00:00",
But when you are running WRF, you have the interval set to:
Code: 
gfdda_interval_m =       360, 360, 360,
so it's wanting to do nudging every 6 hours. The warnings in the output file are simply stating that the input file (wrffdda_d01) has times in between the intervals you've requested on your domain (in namelist.input). So the progression goes...

Simulation starts at 2021-03-22_06:00:00.
When the model is ready to nudge, it looks in the wrffdda_d01 file and sees that time available, and as that is the initial time, it's able to nudge.
Then the model looks in the wrffdda_d01 file again, sees that the next time is 2021-03-22_07:00:00, but since you have a nudging interval of 360, it's not going to nudge at the time 2021-03-22_07:00:00. It does the same again for hours 08, 09, 10, and 11. Once it gets to 12, it's able to nudge again because you have that time in your wrffdda_d01 file, and that is 6 hours from the initial time, which aligns with your nudging interval. This shouldn't cause any problems and it should still be nudging; however, you could potentially change your nudging interval to 60 instead, so that it nudges every hour.
