<div dir="ltr"><div>I've found a few resources online that describe how one can use the USGS NED data within WRF so that 10 m topography can be utilized. However, none of the resources I've found thus far go into great detail on how to go through the process. I might be able to work through it, but figured I would first ask to see if anyone knows of a resource that may explain how to do so in a nice end-to-end manner.</div>
