Model levels to pressure levels

[jlgarcia]

Hi,

This is more of a general query about model levels-to pressure levels.
Could you point to a document that roughly provides a model level to pressure level equivalence?

I am implementing nudging but the configuration is set up based on model levels so I don't really know where I am nudging to.
I've tried to find documentation on how to convert model levels to pressure levels in the UM documentation papers and the NCAS tutorial but I can't find anything.
Other people in my research group have also looked without success.

Any help would be very welcome.
