Further notes on the electron‐density distribution of the upper ionosphere

The problem of obtaining the true electron‐density distribution from the ionospheric virtual‐height data has been treated by the author in several communications [see 1 of “References” at end of paper]. Since then the true electron‐density distribution has been computed for a number of ionospheric records. The nature of the electron‐density distribution of the F2‐layer has attracted much interest during recent years [2]. A publication of some of our later results, therefore, should complete the earlier communications.
