Equivalent of NCL Function "vinth2p_ecmwf" in CDO
Added by Alexander Wikner about 2 months ago
Hello!
I am trying to convert code for post-processing model output on sigma levels to pressure levels from python NCL to CDO. This code relies on the vinth2p_ecmwf function for interpolation and extrapolation below the lowest model level at sigma=0.98329997. I've been trying to use the ml2plx function in CDO for this, but there does not appear to be an option to use the same ECMWF extrapolation method as used in the NCL function and described here: https://opensky.ucar.edu/islandora/object/technotes:168
Is there any way to enable this type of extrapolation in CDO, or is my only option to write this extrapolation method myself using CDO expressions?
Thank you,
Alex Wikner
