z_field

property Workspace.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”.
