The objective is to measure thundercloud electric fields by using the radio emission from the drift of air shower ionization electrons in such fields. The amplitude of the expected radiation has been calculated and a prototype station for making such measurements has been operated. No radio emission associated with air showers could be recognized. This indicates that the very high field regions in thunderclouds are restricted to small volumes. The sensitivity of the apparatus for measurements can be increased by an order of magnitude. That will test much smaller thundercloud fields and will almost certainly yield a positive result. Author
