Questions about altitude and vertical layer

[hiroto]

Hello.
I have some questions about the vertical level of WRF.

1. Unlike the horizontal layer (x, y), is the vertical layer (z) curved rather than a straight surface?
2. Is there a way to output the vertical layer at each altitude in ARWpost? (Output as a straight surface)
3. If num_metgrid_levels = 32 / e_vert = 35, is WRF extrapolating 3 layers over 32 layers?

I'm a beginner, thank you

WRF uses terrarin-following coordinate, so yes, the vertical layer is "curved" instead of a flat surface

2. Is there a way to output the vertical layer at each altitude in ARWpost? (Output as a straight surface)
wrfout includes the variables PH and PHB, (PH + PHB)/9.8 gives you the height of model levels

3. If num_metgrid_levels = 32 / e_vert = 35, is WRF extrapolating 3 layers over 32 layers?

It is not extrapolation. REAL program will interpolate data on metgrid levels to wrf eta levels.

It was very helpful. I was mistaken. I'm glad you noticed. Thank you!
