ppath

property Workspace.ppath

The propagation path for one line-of-sight.

This variable describes the total (pencil beam) propagation path for a given combination of starting point and line-of-sight. The path is described by a data structure of type Ppath. This structure contains also additional fields to faciliate the calculation of spectra and interpolation of the atmospheric fields.

The data struture is too extensive to be described here, but it is described carefully in the ARTS user guide (AUG). Use the index to find where the data structure, Ppath, for propagation paths is discussed. It is listed as a subentry to “data structures”.

Usage: Output from ppath_agenda.
