Аннотация
The absorption of decimeter (DM) radio waves (wavelength ~19 cm) in the high-latitude lower ionosphere of the Earth is found based on analysis of FORMOSAT-3/COSMIC radio occultation data. A method is proposed to reconstruct the vertical profiles of the absorption coefficient by solving the inverse problem of radio sounding in the Earth’s lower ionosphere. This method is general and can be used for different radio wave bands and other global navigation satellite system (GNSS) signals. During radio occultation sessions the absorption layers, which are caused by powerful X-ray bursts and strong changes in geomagnetic conditions during storms, are reliably identified. It is also found that at altitudes of ~90 to ~100 km, the absorption coefficient of DM radio waves reached values of (5.7 ± 1.4) × 10^–3 dB/km. The practical significance of studying the effects of radio wave absorption in the D- and E-regions of the ionosphere is associated with ensuring smooth operation of space radio communication and navigation systems.
