      A new tomographic method was developed with the main goal of mapping the ionosphere in the region of Brazil. The ionospheric background was estimated based on ionosonde and radio-occultation measurements to overcome the ...
    • Spatial and temporal features of the topside ionospheric electron density by a new model based on GPS radio occultation data 

      Prol, Fabricio dos Santos; Hernández Pajares, Manuel; Camargo, Paulo de Oliveira; Honorato Muella, Marcio Tadeu de Assis (2018-03)
      Article
      Open Access
      A new method for probing the spatial and temporal features of the topside ionosphere is presented. The Vary-Chap model given by linear functions was used to discover and report features of the topside scale height and its ...
    • St. Patrick’s Day 2015 geomagnetic storm analysis based on Real Time Ionosphere Monitoring 

      García Rigo, Alberto; Roma Dollase, David; Hernández Pajares, Manuel; Li, Zishen; Terkildsen, Michael; Ghoddousi Fard, Reza; Dettmering, Denise; Erdogan, Eren; Haralambous, Haris; Beniguel, Yannick; Berdermann, Jens; Kriegel, Martin; Krypiak-Gregorczyk, Anna; Gulyaeva, Tamara L.; Komjathy, Attila; Vergados, Panagiotis; Feltens, Joachim; Zandbergen, René; Olivares, German; Fuller Rowell, Tim; Altadill, David; Blanch, Estefania; Bergeot, Nicolas; Krankowski, Andrzej; Agrotis, Loukis; Galkin, Ivan; Orus-Perez, Raul; Prol, Fabricio dos Santos (2017)
      Conference lecture
      Open Access
      A detailed analysis is presented for the days in March, 2015 surrounding St. Patrick’s Day 2015 geomagnetic storm, based on the existing real-time and near real-time ionospheric models (global or regional) within the ...
    • Tomographic imaging of ionospheric plasma bubbles based on GNSS and radio occultation measurements 

      Prol, Fabricio dos Santos; Hernández Pajares, Manuel; Honorato Muella, Marcio Tadeu de Assis; Camargo, Paulo de Oliveira (Multidisciplinary Digital Publishing Institute (MDPI), 2018-10-01)
      Article
      Open Access
      Total electron content measurements given by the global navigation satellite system (GNSS) have successfully presented results to capture the signatures of equatorial plasma bubbles. In contrast, the correct reproduction ...
