Introduction to the Ionosphere: Transcript

Julie A Feldt CEDARGEM workshop June 26 th 2011 Summary Earths atmosphere Ionosphere facts Structure Altitude Latitude Processes Further Reading Ionosphere Facts Ionized upper atmosphere that acts as the interface between earth and space environments. Introduction The ionosphere is a highly variable and complex physical system. It is produced by ionizing radiation from the sun and controlled by chemical interactions and transport by gion between 25 How to snag that DX!. Michael Smith, N5TGL. Agenda. Purpose.
