Title: | Quasi-five- and ten-day oscillations in f0F2 and their possible connection with oscillations at lower ionospheric heights | Issue Date: | Aug-1996 | Series/Report no.: | 4/39 (1996) | URI: | http://hdl.handle.net/2122/1637 | Keywords: | upper ionosphere 5 and 10 day oscillations |
Subject Classification: | 01. Atmosphere::01.02. Ionosphere::01.02.99. General or miscellaneous | Abstract: | The statistical analysis of the 5-day and 10-day oscillations inferred in the upper and lower ionosphere in Central Europe from f0F2 measured in Pruhonice and the radio wave absorption in the lower ionosphere shows a remarkable degree of similarity for relative amplitudes of oscillations (not for absolute amplitudes). The relative amplitudes in both regions do not express a significant solar cycle effect and their seasonal variation is also similar except for winter. The typical relative amplitude of both 5- and 10-day oscillations in the F2-region is about 4%, which is useful information for PRIME. |
