Ionosphere and Applied Aspects of Radio Communication and Radar
Author: Nathan Blaunstein
Publisher: CRC Press
ISBN: 1420055178
Category : Computers
Languages : en
Pages : 600
Book Description
A Complete Reference for the 21st Century Until recently, much of the communications technology in the former Eastern bloc countries was largely unknown. Due to the historically competitive nature of East/West relations, scientific groups operated independently, without the benefit of open communication on theoretical framework

Role of Chemical Effects in Daytime High Latitude Trough Formation
Author: Christopher Sherman
Publisher:
ISBN:
Category : Atmospheric chemistry
Languages : en
Pages : 22
Book Description
The role of enhanced chemical reaction rates in the formation of the daytime F-region trough is examined. A simple convection model is used to estimate the maximum likely elevation of effective temperature for the ion reaction O+ + N2 yields NO(+)+ N. Under extreme conditions the effective temperature can reach 4000 k resulting in a 30-fold increase in the reaction rate. However, the resulting reduction in F-region electron density is only a factor of 4. Under more usual conditions, the reduction is less than a factor of 2. The actual density reduction factor in the daytime trough is observed to vary between 3 and 10 under normal conditions. Therefore, we conclude that under most circumstances, convection-enhanced chemistry contributes very little to the formation of the daytime trough.
