[gradsusr] Zinterp() for vertical interpolation says that it works with sigma levels? Any hints?

[Howard Staines]

I have 0.5 degree data ... with New Zealands busy topography I was thinking 
That using sigma level temperature data (variable tmpsig995).
I think there is an issue in that it isn't a 3d variable so interpolation
doesn't work.

What I am trying to do is remove or ease cold surface temperatures from
surrounding 
high ground leaking into adjacent grid points of significantly lower points.

Solutions appreciated
