Hi All,

I am about to do a double nested 4 day wrf simulation on the cheyenne system. Due to the 12 hr wall time limit, I will have to create restart files and have multiple wrfoutput files for my domains. I was wondering, if there is a way/ an application to merge all wrfoutput files as one for each domain? This way, I can only have one wrfoutput file for each of my domains for plotting.

My input data is the gfs reanalysis grb 2 data.
Please let me know at your earliest convenience.
Yes, you should be able to use the NCO tools ( and commands to concatenate the files after they have been written out. For instance, this command should work to combine 2 files:


Then the '' file would contain data from the times in both 'file1' and 'file2'. You could do this with all of the files you need in a single file.
