## Challenge Activity: your own design continuation

Note: you should only attempt this activity after you have completed this week's Tutorial.

Last week, you created your own experiment design in the Challenge Activity. Now, let's process some LBC data to be used for your setup:

First, you will need to enter the directory where you saved your experiment:

$cd$ cd WRF

$cd <directory where you saved your experiment>$ cd WPS

Then go ahead and edit your namelist.wps so that the start and end dates correspond to the number of domains you have and for the dates you have available in your LBC. Let's work with a simulation from 25 April 2008 at 00 UTC to 27 April at 18 UTC.

After that, you will need to run:

1. ungrib.exe - remember to link the data files and copy the Vtable
2. metgrid.exe

In addition to that, remember to clean up unnecessary files after you run metgrid.exe. The instructions for that are given in the Conclusion section of this week's Tutorial.

If you have any questions or difficulties along the way, feel free to post them on our Facebook group discussion.
