摘要
The height integrated current density in the electrojet over Thumba has been measured between the years 1966 and 1976 on nine different occasions by rocket-borne magnetometers. Using this data and the H variation data from a spread of ground magnetic stations in the region of the electrojet, the depth of the non-conducting layer has been evaluated. The results are compared with the results obtained from POGO and Kosmos 321 satellite experiments. It is shown that the depth of non-conducting layer in the region around Thumba is 230 ±20 km. Using the above data, the internal and the external contributions to the diurnal variation of geomagnetic field observed at the ground have been evaluated. © 1979, Society of Geomagnetism and Earth, Planetary and Space Sciences.
