Installation

pip install acom_music_box

Command line tool

MusicBox provides a command line tool that can run configurations as well as some pre-configured examples. Basic plotting can be done if gnuplot is installed.

Checkout the command line options

music_box -h                                        

Run an example. Notice that the output, in csv format, is printed to the terminal.

music_box -e Chapman

Output can be saved to a csv file and printed to the terminal.

music_box -e Chapman -o output.csv

Output can be saved to a csv file and the terminal output can be suppressed by specifying the --output-format

music_box --output-format csv -e Chapman -o output.csv

Output can be saved to a file as netcdf file when --output-format netcdf is passed

music_box --output-format netcdf -e Chapman -o output.nc

Output can be saved to a file in csv format when a filename is not specified. In this case a timestamped csv file is made

music_box --output-format csv -e Chapman

Output can be saved to a file in netcdf format when a filename is not specified. In this case a timestamped netcdf file is made

music_box --output-format netcdf -e Chapman

You can also run your own configuration

music_box -c my_config.json

Plotting

Some basic plots can be made to show concentrations throughout the simulation

matplotlib

music_box -e Chapman -o output.csv --plot O1D

You can also make multiple plots by specifying groupings of species

music_box -e TS1 --plot O3 --plot PAN,HF 

Note that the windows may overlap each other

By default all plot units are in mol m-3. You can see a list of unit options to specify with --plot-output-unit

music_box -h

It is used like this

 music_box -e TS1 --output-format csv --plot O3 --plot-output-unit "ppb"

gnuplot

If you want ascii plots (maybe you're running over ssh and can't view a graphical window), you can set the plot tool to gnuplo (--plot-tool gnuplot) to view some output

music_box -e Chapman -o output.csv --plot O1D --plot-tool gnuplot
