Patent ID: 8502727

Claim:
A method of correcting a reflectivity measurement using processing steps performed by a weather radar, the reflectivity measurement being associated with a resolution volume, the method comprising: acquiring the reflectivity measurement Z m (i) corresponding to the current resolution volume; estimating the attenuation k c introduced by the cloud droplets, said estimating being carried out by using an average vertical profile of the cloud liquid water content; estimating the attenuation k g,O2 introduced by dioxygen; estimating the attenuation k g,H2O introduced by the water vapor; determining the total specific attenuation k due to the non-detectable components taking into account the attenuation k c , the attenuation k g,O2 and the attenuation k g,H2O estimated in the preceding steps; and correcting the measured reflectivity taking into account the estimated total specific attenuation k.
