Download or read book Analysis of Ionospheric Vertical Soundings for Electron Density Profile Data written by J. W. Wright and published by . This book was released on 1959 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: A tentative model for the F region above hmax is provided to permit extrapolation of electron density profiled into this region. The model corresponds to a simple "Chapman" curve, and may be fitted to true height data (obtained in Part 1) by a simple graphical process.
