    Notes: Summary The effect of the uncertainty and variability in the absorption cross-section, ionization cross-section and the Lyman-α line shape on the Lyman-α ionization-rate calculation is studied. The effect of the variability of the Lyman-α line shape seems to be negligible. The effect of the ionization cross-section is rather small. The greatest and very significant effect, particularly at lower altitudes, is due to the discrepancy in the absorption cross-section data. Some ionospheric and atmospheric consequences are briefly discussed.

    The interplanetary magnetic field sector structure and meteorological microseisms (1977)
    Springer

    ISSN: 1573-1626

    Notes: Summary Meteorological microseisms, recorded at the Prague seismic station and, similarly, at other Central Europe stations, reflect certain meteorological situations in the North Atlantic frontal zone. Meteorological elements in this zone are affected by some factors of extra-terrestrial origin, among others by the interplanetary magnetic field (IMF) sector structure. The analysis of the 68 IMF sector boundary passage effects in microseismic activity, expressed in microseismic amplitudes, showed a well-developed minimum of microseismic activity on the day of the boundary passage in winter, but no such effect in spring and autumn. In spring and autumn, however, a tendency was observed to slightly higher microseismic activity in the “away” (+) sector, whereas no such tendency was observed in winter. These results agree with the IMF effect found in the troposphere. Generally, the IMF sector structure is only a modulating rather than a major factor controlling the microseismic activity.

    Diurnal asymmetry in the lower ionosphere — seasonal variability (1978)
    Springer
    Studia geophysica et geodaetica 22 (1978), S. 309-313 
    Details
    ISSN: 1573-1626

    Topics: Architecture, Civil Engineering, Surveying , Geosciences , Physics
    Notes: Summary On the basis of long period measurements of ionospheric absorption in five A3 circuits in Central Europe, it is shown that the considerable seasonal variation of the diurnal asymmetry of absorption, found in[1], exhibits practically no year-to-year variability and is well-developed at equivalent frequencies f eq ≲1 MHz, while it vanishes at F eq ≲2 MHz. The limited data on the diurnal asymmetry of the D-region electron concentration are consistent with the seasonal pattern of the diurnal asymmetry in absorption. A tentative hypothesis of nitric oxide variability as the cause of the seasonal variation of the asymmetry is proposed.

    A3 ionospheric absorption measurements at 1538 kHz — first results (1978)
    Springer
    Studia geophysica et geodaetica 22 (1978), S. 390-401 
    Details
    ISSN: 1573-1626

    Topics: Architecture, Civil Engineering, Surveying , Geosciences , Physics
    Notes: Summary A series of absorption measurements covering more than two years, carried out by the A3 method (oblique incidence) on 1538 kHz at the Panská Ves Observatory, is studied. The measuring equipment is shortly described, as well as calibration and the measuring path. Both the diurnal variation of absorption, including its asymmetry, and the seasonal variation of absorption, including the winter anomaly, are observed in a predicted form. The computed height profile of absorption shows that nearly all the absorption is formed in the middle and upper D-region. The 1538 kHz absorption measurements could serve as a very good tool for studying the D-region, but there are still some difficulties attributed to the determination of the zero level of absorption. Suggestions are given how to remove this difficulty.

    Notes: Summary The meteorological microseisms recorded at Prague are found to be essentially independent of the occurrence of the major midwinter stratospheric warmings. This finding contributes to studying the downward propagation mechanism of some extraterrestrial influences.

    Ionospheric effects of the December 16–18, 1971 geomagnetic storm (1979)
    Springer

    Notes: Summary The post-storm effect (PSE) of the December 16–18, 1971 geomagnetic storm is studied with the use of the ionospheric radio wave absorption measurements and f min data from a network of the GDR, USSR and Czechoslovak observatories. Only a high latitude effect of the storm was found. We found more significant absorption effects associated with later weaker enhancements of geomagnetic activity. The part played by the interplanetary magnetic field is demonstrated. A magnetospheric explanation of the observed variability of PSE based on the time-development of filling up the slot region is suggested.

    SEA and SDA measurements at panská VES — peculiar Events (1979)

    Notes: Summary The results of the twelve-year (1962–1973)SEA (27 kHz) andSDA (5 kHz) measurements at the Panská Ves Observatory are presented with an emphasis on peculiar events. About half of allSIDs are observed asSEA events and about 10% asSDAs. NoSID has been observed only as anSDA. A fewSIDs have been observed asSEA only, most of them being probably of non-solar origin. A few events observed asSEA andSDA only, or as anSID withSDA, but withoutSEA, are briefly discussed, too.

    Improved indirect phase reflection height measurements at Panská ves - first results (1992)
    Springer
    Studia geophysica et geodaetica 36 (1992), S. 358-369

    ISSN: 1573-1626

    Notes: Summary Indirect phase reflection height measurements have been performed at the Panská Ves Observatory, Czechoslovakia, on two frequencies of 162 (earlier 164) and 153 kHz (earlier 155) for 30 years. However, they were used only for solar flare effect (SFA) monitoring. After introducing new measuring equipment in 1985, the quality of the 162 kHz records became sufficient to apply the indirect phase height analysis (IPHA) method in full. The method itself, the measuring equipment, and the method of evaluation are described in [1]. The purpose of this paper is to describe the first results and to verify the reliability of the 162 kHz IPHA data. The IPHA method as applied to the 162 kHz measurements made at Panská Ves, allows ionospheric and neutral atmospheric parameters to be studied simultaneously and appears to provide reliable and good quality data. The expected seasonal variation and response to sudden stratospheric warmings are observed. The use of the 162 kHz IPHA data in the international MAC/SINE and DYANA campaigns and for monitoring pressure variability at 80 km are briefly described.
