Process WRF output files individually and then use "cat" to merge all the ARL formatted files together.

Thank you Fantine. It worked.
The next problem I am getting is while running the main hycs_std model. I am getting the following error .

" HYSPLIT4 - Initialization
USE: svn info | tail -n3
to fill in these three records
with the version information!
ERROR metset: meteorological data time interval varies. Check input meteo file.
Changed from 60 min to 1440 min
At day/hr 30 0
STOP 23 "



I checked the times in the WRF and the met input file and it is all hourly interval only.
Can't find the source of this error.
Please help.

When you merge ARL formatted files, make sure it was done orderly.
Use "chk_times" to check if all the time steps in the file are in a correct time sequence.

Hello,

This is Saroj Dhital. I saw the post regarding the conversion of WRFOUT to ARL and I have a similar problem during conversion.

I am trying to convert 6-hr WRF output single file(1-hr output) to ARL format. When I tried to convert it, I got the following error:

Processing started ...

Starting to convert: C:/hysplit4/working/wrfout_d02_2008-10-08_06_00_00
Program directory : C:/hysplit4/exec

Using an existing decoding configuration: WRFDATA.CFG
C:/hysplit4/working/wrfout_d02_2008-10-08_06_00_00 : NetCDF: Unknown file format

Finished: C:/hysplit4/working/wrfout_d02_2008-10-08_06_00_00




I did the same process for the 6-hour output file (6-hr output) and worked well, however, did not work for 6hr output.

Do you have any idea regarding this issue? Do I need to specify the time in arw2arl.F file?
Thank you very much in advance.

Are you able to process the WRF file containing data for 6 hours now?
For running arw2arl for a multiple-time-step file, you need to specify the time period. The program will process all the time steps in the file.
