Positive and negative ion profiles, together with the λ-profile (ratio of negative ions to electrons), have been derived for Thumba (8°54′N) for noon conditions and for the height range 50–90 km, using the latest available input parameters. 相似文献

The computed photoionization rates in the discrete wavelength bands in the XUV spectra under quiet sun, moderate flare, strong flare and outstanding flare conditions have been presented graphically as a function of altitude in the height range 50 – 90 km to show the relative importance of solar X-rays below 10 Å. Ionospheric absorption data, measured by A1 technique at the Ionosphere Research Centre at the University of Delhi, Delhi (28.6°N) at a single radio wave frequency of 2.132 MHz have been analyzed under solar flare conditions, with a special emphasis on a solar flare event on 3 February, 1983 which started at 1115 IST, reached its peak at 1140 IST and persisted till 1400 IST, during which time the radio wave absorption exceeded 60 or 65 dB for nearly three and half hours. During solar flare, a direct correlation between large enhancements of solar X-ray flux and ionospheric absorption is observed. 相似文献
