An application to two rivers shows that the point estimates are very close to the corresponding values computed by hydrologists, based on historical data. Moreover, by modifying the values of the parameters in the model, we can see the potential effects of climate change on the return pe [...] 2469 10130 |
Variations in the Maximum Electron Density of the F2 Layer (NmF2) over the Middle Latitude Station of Grahamstown, South Africa, during Solar Cycle 23by
Abstract
Ultraviolet (UV) and X-ray radiation are the primary causes of ionization that produce electron density in sufficient quantities to promote the propagation of satellite radio signals in the ionosphere. The electron densities suffer from spatio-temporal variations, and this poses different degrees of threats to satellite radio signals propagating through the ionosphere. We aimed to characterize the maximum electron density of the F2 layer (NmF2) in the middle-latitude ionosphere over Grahamstown, South Africa (Geogr [...] 1691 9871 |
