Class HybridHeight

java.lang.Object

ucar.unidata.geoloc.vertical.VerticalTransformImpl

ucar.unidata.geoloc.vertical.HybridHeight

All Implemented Interfaces:

VerticalTransform

public class HybridHeight
extends VerticalTransformImpl

Create a 3D height(z,y,x) array using the netCDF CF convention formula for "Atmospheric Hybrid Height".

height(x,y,z) = a(z) + b(z)*orog(x,y)
