Die Frequenzabhängigkeit der ionosphärischen Absorption

摘要: Detailed analysis has shown that in most cases where observations did not follow the writers' old formula L = B/(f + fL)2 N . Δ3(f0E/f), intense echos from a blanketing Es-layer were present. The theory is generalized to case of thin, mirror-like embedded into parabolic E-layer (model D). This gives new function depending on second parameter given by altitude mirror. By application (with actual parameters each observation) we obtain much better description observed frequency variation. Noon values B (non-deviative D-absorption and (deviative E-absorption) show opposed seasonal variations, increasing but decreasing with sun's height. variation can be explained satisfactorily small decrease height sun.
