Workspace Variable lon_true

Longitudinal geolocation for 1D and 2D data.

The variables lat_grid and lon_grid contain true positions only
for 3D. For 1D and 2D, the geographical position is given by
lat_true and lon_true. Can be left empty when not used.
Otherwise:

   1D: lon_true shall have length 1

   2D: Both lat_true and lon_true shall have a length matching
       lat_grid. That is, lat_true and lon_true shall not be
       seen as grids, they are vectors giving the actual lat or lon
       for each point corresponding to lat_grid.

Usage: Set by the user.

Unit:  degrees

Default: []

Group: Vector
