Research Abstract

In this study, we addressed an estimation problem of the electron density profile on the lunar surface from spectrograms of natural plasma waves observed by the KAGUYA spacecraft. As a result, the moon does not have global and steady dense plasma layers which become an evidence of the lunar ionosphere.
