The Earth’s ionosphere consists of plasma produced by the photoionization of thin upper atmospheric gases by UV rays and photons of short wavelength from the sun. The upper ionosphere is used for radio communication and navigation as it re-ects long, medium, as well as short radio waves. Since solar radiation is the main cause of the existence of ionosphere, any variation in the radiations can affect...
We investigated the diurnal, seasonal and latitudinal variations of ion density Ni over the Indian low and equatorial topside ionosphere within 17.5°S to 17.5°N magnetic latitudes by combining the data from SROSS C2 and ROCSAT 1 for the 9year period from 1995 to 2003 during solar cycle 23. The diurnal maximum density is found in the local noon or in the afternoon hours and the minimum occurs in the...
