Extracts complex refractive index from a field of such data.

The method allows to obtain surface_complex_refr_index by interpolation of a geographical field of such data. The position for which refraction shall be extracted is given by rtp_pos. The refractive index field is expected to be stored as:

  • GriddedField5:

    • Vector f_grid[N_f]

    • Vector T_grid[N_T]

    • ArrayOfString Complex[2]

    • Vector “Latitude” [N_lat]

    • Vector “Longitude” [N_lon]

    • Tensor5 data[N_f][N_T][2][N_lat][N_lon]

Definition and treatment of the three first dimensions follows complex_refr_index, e.g. the temperature grid is allowed to have length 1. The grids for latitude and longitude must have a length of >= 2 (ie. no automatic expansion).

Hence, this method performs an interpolation only in the lat and lon dimensions, to a single point. The remaining GriddedField3 is simply returned as surface_complex_refr_index.
