1. A method of estimating precipitation characteristics comprising:

  • acquiring a radar image including at least a vertical plane of a precipitation zone;

    processing via a computation unit a vertical profile of said precipitation zone to generate digital signals representative of reflectivity in vertical direction z;

    integrating via the computation unit the signals representative of reflectivity by assimilation of a reflectivity vertical profile in an aggregation model to generate a signal representative of the profile in the vertical plane of a mean particle diameter weighted by mass of each particle; and

    determining via the computation unit and displaying on a display device connected to the computation unit, concentration of the solid particles on the basis of signals representative of the profile in a vertical plane of a mean particle diameter weighted by mass of each particle.
