question about merge arl files

[lovechang1986]

the wrfout so large (one file has 600M). while i want to convert one time wrfout to arl file format, and then merge all the arl files.
is there any way to sovle?

When running arw2arl, you can set option -b and -e to process the desire hour in the WRF file.
-b[beginning time period index (1)]
-e[ending time period index (9999)]
If not setting these two options, the program will process all time steps in the WRF file.

@Fintine Because my wrfout are many single hour nc file, one file has 600M, so I don't want to merge the wrfout file together.

just convert all the wrfout file, and the merge all of arl files?

[Fantine]

if you have multiple ARL format files converted from several WRF files, you can simply merge the ARL files using "cat" for linux/unix computing environment.
