Does the REAL program generate the Full level height based on the International Standard Atmosphere?

[Remnant]

Hello there.

I'm trying to add more vertical levels in WRF. I run REAL and get the following eta levels in rsl.out:
1.0000 0.9941 0.9876 0.9805 0.9727 ...
Full level index = 1 Height = 0.0 m
Full level index = 2 Height = 50.0 m Thickness = 50.0 m
Full level index = 3 Height = 104.9 m Thickness = 54.9 m
Full level index = 4 Height = 165.2 m Thickness = 60.3 m
Full level index = 5 Height = 231.5 m Thickness = 66.3 m
...
From what I understand, the height of each model level in the Hybrid Vertical Coordinate changes with surface pressure and surface dry pressure. Does the REAL program generate the Full level height based on the International Standard Atmosphere? Or am I misunderstanding HVC?

Thanks.

Hi,
I first would like to apologize for the long delay in response. We have been occupied with preparing for our upcoming code release and have gotten behind with forum posts. Thank you so much for your patience.

The heights printed in the rsl* files are only for guidance. They come from PHB, which is the base state.

Thanks, Kwerner. I also found the detailed calculation process in the WRF/dyn_em/module_initialize_real.F program. Looking forward to your new code release!
