Abstract :
20 GHz signals received from the ATS6 satellite show much higher crosspolarisation than expected from rain alone. Radar data indicate the cause to be hydrometeors above, rather than in, the melting band. During thunderstorms, the crosspolar level can change abruptly at the moment of a lightning discharge.
