Any way to run this at even higher resolution, like 1 km? Could this resolve terrain forced effects like lenticular clouds on mountain tops?

One big problem is input weather data. It's resolution is poor.

Yeah, not to mention trying to validate results. Unless we grid install weather stations every 200 m on a mountain top...
