Amateur Radio

Dr. Damien Chua works at the Naval Research Laboratory. "I will present a survey of ionosheric variability and its effects on RF Communications. We will first review the process of radio wave propagation and reflection in the ionosphere. We will then examine how the ionosphere varies spatially and over various timescales. The drivers of ionospheric variability will be traced out through the Earth's magnetosphere and into interplanetary space to their solar origins. We will review space weather measurements and indices available to the amateur radio community and will provide some interpretation of them for understanding the space weather effects discussed above".
