Variation of ionospheric slab thickness over South Africa
Ionospheric slab thickness is defined as the ratio of TEC to maximum electron density of the F-region (NmF2), proportional to the square of the F2-layer critical frequency (foF2). It is an important parameter in that it is linearly correlated with scale height of the ionosphere, which is related to electron density profile. It also reflects variation of the neutral temperature. Therefore, ionos...
متن کاملIonospheric slab thickness – analysis, modelling and monitoring
A review of the climatological and storm-time behaviour of the ionospheric slab thickness is presented based on long-time observations at a European mid-latitude site, Dourbes (50.1°N, 04.6°E), and on published results from other studies. An operational electron density and slab thickness monitoring system, established to provide real-time characterisation of the local ionospheric dynamics, is ...

متن کاملThe climatology of ionospheric plasma bubbles and irregularities over Brazil
In this paper, we examine ionospheric plasma depletions (or bubbles) and irregularities observed by photometers and a ground-based receiver of the global positioning system (GPS) both located in Brazil, South America. A simultaneous observation reveals that when the ionospheric plasma becomes depleted, the GPS total electron content decreases and the associated phase fluctuations grow. Statisti...
متن کاملThickness Dependence of Galvanomagnetic Properties in a Very Thin Slab
The thickness dependence of the magnetoresistance and the Hall constant is obtained in the twoband model with compensating charge carriers by using a specific perturbation formalism for quasitwo-dimensional systems. Screened impurity scattering is considered within the Boltzmann kinetic equation scheme, and the relaxation time is evaluated as a function of thickness through the scattering ampli...
