Imaging of the equatorial ionosphere
The equatorial anomaly is the dominant structure in free electron concentration in the tropical ionosphere. Due to its edges (crests) which are characterised by steep latitudinal gradients in TEC and are temporally and spatially variable, it is one of the ionospheric regions most difficult to image with inversion methods. In this paper we reconstruct an International Reference Ionosphere model ...
متن کاملCorrelation Structure of the Equatorial Ionosphere
With the successful implementation of the Wide Area Augmentation System (WAAS) for the North America, there is interest in implementing similar systems in other parts of the world. The ionosphere over certain parts of the globe, notably equatorial regions and Brazil in particular, can have a far greater impact on the signals received from the satellites. The Ionospheric corrections form an inte...
متن کاملSystematic study of intermediate-scale structures of equatorial plasma irregularities in the ionosphere based on CHAMP observations
*Correspondence: Hermann Lühr, GFZ, German Research Centre for Geosciences, Section 2.3, Earth’s Magnetic Field, Telegrafenberg, 14473 Potsdam, Germany e-mail: [email protected] Equatorial spread-F ionospheric plasma irregularities on the night-side, commonly called equatorial plasma bubbles (EPB), include electron density variations over a wide range of spatial scales. Here we focus on int...
متن کاملFinite-Difference Time-Domain Simulation of Light Propagation in 2D Periodic and Quasi-Periodic Photonic Structures
Ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. Therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. We...
متن کاملResponse of Equatorial Oceans to Periodic Forcing
Oscillating wind with a period P induce variability with the following characteristics in the upper few hundred meters of the equatorial zone (5øN to 5øS) of the ocean. (1) P < 10 days: these winds fluctuate too rapidly to generate strong currents and excite primarily waves. (2) 10 days < P < 50 days: At these periods the winds generate intense equatorial jets in the upper 50 m, but at greater ...
