Includes one atmospheric wind component in the Jacobian.

The method follows the pattern of other Jacobian methods. The calculations can only be performed by analytic expressions. Some lower level function depends on frequency perturbations, however, so therefore a frequency perturbation df is required and as a consequence abs_f_interp_order must be > 0.

The wind field components are retrieved separately, and, hence, the argument component can be “u”, “v” or “w” for vector components, or just “strength” for total wind speed.

The number of elements added to the state vector (x) is:

n_g1 * n_g2 * n_g3

where n_g1, n_g2 and n_g3 are the length of GIN g1, g2 and g3, respectively. Here empty vectors should be considered to have a length 1. The elements are sorted with pressure as innermost loop, followed by latitude and longitude as outermost loop.
