摘要:
The conductivity of the atmosphere has been measured during flights in aeroplanes near ground level and up to about 16,000 ft. Seven flights were made during the autumn and winter of 1936–1937. The Gerdien type of conductivity apparatus was used. An attempt was also made to measure potential gradients by the radioactive collector method. This method was impractical, probably because of charges acquired by the aeroplane. It did, however, serve to indicate the presence of intense local space charges such as charged clouds. On one flight, observations were taken near a thunderstorm, but owing to difficulties in interpretation no conclusions regarding the exact nature or location of the charges could be drawn. The conductivity increased rapidly with height in a manner in general agreement with the data of other observers. Positive and negative conductivities were found to be equal, within the experimental error, at heights between about 1000 and 10,000 ft. At higher altitudes the negative conductivity was greater than the positive. The presence of clouds and frontal discontinuities usually caused a reduction in continuities.
