1. A method of correcting a reflectivity measurement performed by a radar such as a weather radar, the reflectivity measurement being associated with a resolution volume, the method comprising:

  • analyzing the current resolution volume to determine whether the plane representing the 0°

    C. isotherm passes through the resolution volume;

    when the plane representing the 0°

    C. isotherm passes through the current resolution volume, dividing said resolution volume into two portions lying on either side of said plane, and determining an attenuation associated with the resolution volume by taking into account the contribution of each of the portions to measured reflectivity; and

    correcting the reflectivity associated with the current resolution volume using the attenuation thus determined;
