z_surface
- property Workspace.z_surface
The surface altitude.
This variable defines the shape of the surface, by giving the geometrical altitude above the geiod for each crossing of the latitude and longitude grids. Any shape of the surface is accepted. No gap between the surface and the lowermost pressure level is allowed.
The radius (from the coordinate centre) for a point between the grid crossings is obtained by a linear (1D) or bi-linear (2D) interpolation of the sum of the ellipsoid radius and
z_surface
. That is, the radius for the surface is assumed to vary linear along the latitudes and longitudes inlat_grid
andlon_grid
.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”.
Usage: Set by user.
Unit: m
Dimensions: [ lat_grid, lon_grid ]
