Riometry as an Aid to Ionospheric Forecasting


Book Description

The report deals with the use of riometers as an aid in ionospheric forecasting during both disturbed and undisturbed conditions at various geographical regions of the earth. Both the physical and technical aspects of riometry are discussed. Riometer observations during special solar geophysical events such as polar cap absorptions, auroral absorptions, and solar flare effects are presented and discussed. Suggestions for the improvement of riometer output and a description of experiments to be performed using riometers as an integral part of forecasting systems are presented. (Author).

Ionospheric Prediction and Forecasting


Book Description

This book describes how to predict and forecast the state of planet Earth’s ionosphere under quiet and disturbed conditions in terms of dynamical processes in the weakly ionized plasma media of the upper atmosphere and their relation to available modern measurements and modelling techniques. It explains the close relationship between the state of the media and the radio wave propagation conditions via this media. The prediction and forecasting algorithms, methods and models are oriented towards providing a practical approach to ionospherically dependent systems design and engineering. Proper understanding of the ionosphere is of fundamental practical importance because it is an essential part of telecommunication and navigation systems that use the ionosphere to function or would function much better in its nonappearance on the Earth and on any planet with an atmosphere.

Ionospheric Delay Investigation and Forecasting


Book Description

This book highlights ionospheric delay investigation and forecasting using GPS-TEC measurements in the equatorial region. The ionospheric delay error is the main source of error and a major concern for GPS applications as it corrupts the positioning and time transfer results. In the equatorial region, the variations of the total electron content (TEC) and the ionospheric delay are recognized to be high when compared with other regions such as mid-latitude and high latitude. The investigation and forecasting of trans-ionospheric propagation errors are essential for precise measurement and further contribute valuable information to satellite and space probe navigation, space geodesy, radio astronomy and other applications.
