On the Measurement of Air-Earth Current at Kakioka


Misaki, M., Kawamura, M. & Kondo, G.


Abstract

 Recently, it has been emphasized by H. Israel and G. Lahmyer (1)and others that the continuous simultaneous observation of the three essential elements of atmospheric electricity, i.e. potential gradient, conductivity and air-earth current, is very important and
  necessary to study the origin of the world-wide atmospheric electric phenomena and the role of the undisturbed region on the maintenance of the earth's negative charge.
  The last thirty years, the serial registration of potential gradient and the temporary eye-observation of conductivity are continued at Kakioka Magnetic Observatory. Now, it was chanced to realize in this International Geophysical Year that we observe continuously
  the air-earth current and conductivity. In present paper, we describe in detail of the principles of measurement of the air-earth current and of the operation of its measuring apparatus for the convenience of handling of it.
