Hi everyone. How can I merge several concentration output files into one? I have seen a post earlier on the same topic where conappend was recommended. I am quite unfamiliar with batch file scripting and working with command line. It will be a great favor if windows batch file of conappend is provided or if possible a solved example. Please tell if there is some other better option. I have tried doing it but getting error, attaching here the failed attempt. Thanks in advance.

It should work if you just remove all the square brackets.
Also it is better if you run the command in your working directory.
Go to working directory and run

C:\hysplit\exec\conappend -iINFILE -osdump -c1

Thank you so much. It worked

Also another question related to this, which executable to use when we have to sum up cdump outputs day 1 to 30(30 outputs) of a month into one plot showing concentration of pollutant for an entire month?

It sounds like conavgpd is what you are looking for
