Please find enclosed the 31 model level hybrid co-ordinates:

The vertical coordinate parameters define the edges of the atmospheric layers
in terms of the surface pressure (in Pascals). The parameters can be
considered as being true at the mid-point (in pressure) of a layer for
each point.

The values are:

I hope this helps your colleague.
