How to set up a domain from namelist in WRF? I'm fairly inexperienced with WRF and was wondering if anyone could point me in the direction of any helpful resources for it.

The task I have is to make a simple 9 km domain, but I'm having trouble understanding what some of the variables actually do/mean?

Specifically,  e_we/sn , dx/dy , and how a nested domain works.
There is a WRF domain Wizard offered by ESRL. You can download it here. Also, don't make the same mistake I made using Lambert Conformal- keep stand_lon the same as your ref_lon.
