New Insights on the Crustal Deformation in the Eastern Betics From Densified GNSS Data
Tectonics, Volume 44, Issue 2, February 2025.Abstract The Eastern Betic cordillera, southeastern Spain, is characterized by slow tectonic deformation rates and moderate seismicity. Great uncertainties persist regarding the precise kinematics of the main fault system within the region, the Eastern Betic Shear Zone (EBSZ). We present a new GNSS (Global Navigation Satellite System) velocity field in

Long Term Global Ionospheric Total Electron Content Trend Analysis
Geophysical Research Letters, Volume 51, Issue 21, 16 November 2024.Abstract Simulations based on physical models of the thermosphere‐ionosphere system suggest that the ionosphere will sink as the thermosphere cools and contracts in response to increasing greenhouse gas concentrations. As a consequence, long‐term trends can be expected in ionospheric parameters such as: total electron content (TEC), the critical ...

Near‐Real‐Time Identification of the Source of Ionospheric Disturbances
Journal of Geophysical Research: Space Physics, Volume 129, Issue 11, November 2024.Abstract The ionosphere is characterized by a large number of disturbances generated in response to a wide range of phenomena, including natural hazards, space weather and man‐made events. Identification of the origin of ionospheric disturbances (ID), especially in real or near‐real‐time (NRT), is an extremely difficult task, and it is one of the most ...

Space Weather, Volume 22, Issue 11, November 2024.Abstract On 10 May 2024, a severe geomagnetic storm coinciding with Mother's Day in Mexico lasted over 40 hr and produced polar auroras observable at low latitudes. This storm, the most intense since 2003, resulted from a series of solar flares and coronal mass ejections from active region 3664.

Space Weather, Volume 22, Issue 9, September 2024.Abstract This paper investigates time‐lag effects of ionospheric response to two severe geomagnetic storms (Kp = 8) on the degradation of kinematic precise point positioning (PPP) solutions, utilizing over 5500 Global Navigation Satellite Systems (GNSS) stations distributed worldwide. Focusing on these two severe geomagnetic storms that occurred during

Camil Gemael: uma vida dedicada à Geodésia
Revista Brasileira de Cartografia, 2018 É difícil estabelecer exatamente quando se inicia a história da Geodésia Brasileira, mas é certo afirmar que os primeiros trabalhos de posicionamento foram realizados à época do descobrimento.
