Book Description

The book’s purpose is to introduce HF ionospheric radio propagation through the solution of problems and computer assignments. These serve primarily to check and deepen understanding of the theoretical aspects. Secondly, they are used to introduce readers to new subjects in a natural way.

The main objective is to bring readers with a background equivalent to a M.Sc. degree in physics or engineering up to an operative level in the field of ionospheric radio propagation research.

Author Introduction

Carlo Scotto was born in Orbetello (Italy) in 1965. He holds a physics degree from the University of Rome (La Sapienza) and a PhD in Polar Science from the University of Siena. He attended a three-year Scholarship for Specialization in Geophysical Disciplines and is currently a senior researcher at INGV, the Italian National Institute of Geophysics and Vulcanology. He has taken part in two Antarctic campaigns and completed a research appointment at the University of Western Ontario (Canada) during the academic year 2009-2010. Other activities include studies on atmospheric gravity waves, sporadic E layer, irregularities in the F2 region, probability of occurrence of the F1 layer, and contributions to the International Reference Ionosphere model. He introduced a method for the inversion of ionogram traces and is the main author of the Autoscala software for the automatic interpretation of ionograms. To date he has published over 40 papers in peer-reviewed journals.
