get all time step outputs into one history file

[wrfpup]

I am looking at some NCL scripts for plotting MPAS output and it appears they are wanting a single history file for say, a 24h forecast. Right now I have history files output at 3h intervals, but I would like to have one history file that contains each of these history writes (for a 24h forecast) instead. How can one do that? TIA.

To get many times in one output file you can add the 'filename_interval' attribute to an output stream in your streams file and set it to accordingly to your needs. For instance, if your output interval is 2 hours and you set filename_interval to "12:00:00" you would get three files, two with six times each and one with one (after the very final time step). Setting filename_interval to "none" will put all output into a single file.

Here are some examples:

<stream name="output"
        type="output"
        filename_template="history.2562.$Y-$M-$D.nc"
        filename_interval="none"
        output_interval="2:00:00" >

        <file name="stream_list.atmosphere.output"/>
</stream>

<stream name="output"
        type="output"
        filename_template="history.2562.$Y-$M-$D_$h.nc"
        filename_interval="06:00:00"
        output_interval="2:00:00" >

        <file name="stream_list.atmosphere.output"/>
</stream>
