Abstract

F0R some months we have been recording daily the equivalent heights and reflection coefficients of the F2 region of the ionosphere, for radio frequencies near to the critical penetration frequency of the region. Under these conditions, the recorded quantities are exceptionally sensitive to small changes in the electron density of the F2 region.
