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?

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.

@Fantine Thanks!!!!~~~~
