lon_true

property Workspace.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
