The airborne radars can easily follow the observed phenomena and allow to scan meteorological systems in places where ground

ased radars are not easy to operate and they are progressively used in meteorological studies. Due to the requirements of the applications. airborne radars use an X

and or Ku band frequency. However

the electromagnetic wave on the frequency is attenuated through rain

thus algorithms should be studied to correct for the attenuation effect. For the single beam

kZ and kZS algorithms demonstrate a promising interest for application. This paper applies kZ and kZS algorithms to the airborne data gathered in January and February 1993 during the TOGA/COARE experiments and studies the rain structure.
