Vertical interpolation from model levels to pressure levels on SE grid

Officially, its best to output the PMID variable for the se-dycore. But a decent alternative is:
Would that work?

If you need to interpolate to specified pressure levels, I use https://www.ncl.ucar.edu/Document/Functions/Built-in/int2p_n.shtml
Thanks for the pointers.
It looks like there's not yet a replacement or an update to NCL "vinth2p*"
that can use the SE grid.

I'm at the acceptance phase of my grieving ... and had assumed ncl is done making new functions.
The GeoCAT folks have recently implemented vinth2p into python. You could inquire about this functionality by opening an issue: NCAR/geocat-comp

Thanks! Will do.
Hi，
Firstly, I changed the SE grid to lon-lat grid using "ncremap" (NCO operator), then I used NCL "vinth2p" to do the vertical interpolation. But there still had abnormal value near undergrond region in near surface pressure level. Then, I saw the function you mentioned "vinth2p_ecmwf", I found it works in dealing with the abnormal atmospheric value near surface level. Thanks!
I wonder if you know whether there is a convenient way to dealing with the abnormal value near surface topography when using "vinth2p" to interpolate hybrid to pressure? Because I always used "vinth2p" to deal with the vertical interpolation before, and I don't know how to do with the wrong value because of tropography in those data. Thank you again!
Any advice would be appreciated!
If "vinth2p_ecmwf" gives you the results you want, then use it instead of "vinth2p".
Hello, I wonder whether this function can be directly used for vertical interpolation of SE grid data
or I still need to convert the SE grid to lat/lon first (e.g. 'ESMF_regrid' in ncl, can I use this function?),then use 'vinth2p_ecmwf'?

The NCL functions assume a lat/lon grid, so to use them, you'll need to regrid from SE to a lat/lon grid first.
Thank you for your patience！
geocat has done this. See here for the relevant discussion: Vinth2p_ecmwf · Issue #207 · NCAR/geocat-comp
