Ionospheric absorption over southeastern Europe
Abstract
Ionospheric absorption was measured at the Sofia and Roburent stations for a period of up to two solar cycles. A geophysical interpretation is given of radio absorption phenomena for both daytime and nighttime conditions, and it is suggested that the data can be used in the design of radio-communication systems in Bulgaria.
