Climatic variations of the ionospheric absorption of radio waves in the short-wave range
Abstract
Variations of radio-wave absorption were measured with the A3 method on a France-Bulgaria path during 1959-1986, and a systematic increase of this absorption was found. It is shown that the most probable cause of this increase is a decrease of atmospheric temperature in the mesopause region by 5 K over the time period considered.
