Computes the apparent VPR

Parameters:

  • radar (radar object) – the reference radar object

  • ml_top, ml_thickness (float) – melting layer top [m asl] and thickness [m]

  • val_ml (float) – value in the peak of the melting layer

  • val_dr (float) – decreasing ratio above the melting layer

  • h_max (float) – maximum altitude at which to compute the theoretical profiles [m asl]

  • h_res (float) – profile resolution [m]

  • max_weight (float) – the factor by which the antenna beam width is multiplied

  • vpr_theo_dict (dict or None) – A dictionary containing the theoretical VPR profile. If it is None the theoretical VPR profile is computed using the parameters describing it

  • refl_field (str) – Name of the apparent reflectivity profile obtained

Returns:

  • radar_out (radar object) – A radar object containing the apparent normalized reflectivity profile

  • vpr_theo_dict (dict) – A dictionary containg the theoretical normalized reflectivity profile
