TL;DR: In this article, the authors used Sheffield University Plasmasphere Ionosphere Model (SUPIM) with an intensified westward disturbed electric field in the presunrise hours, presumably due to prompt penetration from the magnetosphere, in order to study the effect of such a field in ionosphere.

TL;DR: In this paper, a data-stack of 33 TerraSAR-X images was used to monitor distinct displacement regimes, ranging from small to high deformation rates, and to map surface changes, based on variations of radar reflectivity.

TL;DR: In this article, the authors analyzed data from an array of instruments consisting of Digisondes, a VHF radar, GPS TEC and scintillation receivers in Brazil, and a Digisonde and a magnetometer in Jicamarca, Peru.

TL;DR: In this article, a prototype of a cartographie mobile terrestre bon marche composed of a camionnette, de deux cameras video numeriques, de two recepteurs GPS, d'un carnet de terrain and a systeme fiable de synchronisation des prises de vues is presented.

TL;DR: In this article, a regional ionosfera using selective frequency was used to calculate the position of a point of interest (PS Receptor) in a region of interest in Brazil.
