Did you know?
WebSince scintillations are an indicator for the presence of irregularities of electron density in the ionosphere, the scintillation measurements are used to determine the spatial and temporal distribution of the ionospheric irregularities. WebIts value is not fixed and it depends upon the electron density of the ionosphere. Equations [ edit] Critical Frequency as a Function of Electron Density [ edit] Critical frequency can be computed with the electron density given by: where Nmax is maximum electron density per m 3 and fc is in Hz.
