Workspace Variable z_field

The field of geometrical altitudes.

This variable gives the geometrical altitude, above the ellipsoid, of
each crossing of the pressure, latitude and longitude grids. For 1D
cases the altitudes give the geometrical position of the pressure
levels.

For each geographical position (lat,lon), the values must be sorted
in increasing order, with no repetitions. Otherwise the altitudes
can be set to arbitrary values. Hydrostatic equilibrium is not
applied automatically. If hydrostatic equilibrium applies, z_field
must be set by a method ensuring that this criterium is fulfilled.

The radius (from the coordinate centre) for a point between the grid
crossings is obtained by a (multi-)linear interpolation of the sum
of the ellipsoid radius and z_field.

See further the ARTS user guide (AUG). Use the index to find where
this variable is discussed. The variable is listed as a subentry to
"workspace variables".
