La investigación de nuestro grupo se desarrolla en el ámbito de la electricidad atmosférica y especialmente sobre el fenómeno del rayo. En la investigación básica trabajamos en el estudio de la física del fenómeno del rayo; los acontecimientos luminosos en la alta atmósfera (TLE); las emisiones terrestres de alta energía (TGF);
las emisiones de altas energías en rayos y descargas eléctricas; la actividad de los rayos en tormentas severas, y los campos electromagnéticos producidos por los rayos. También realizamos investigación aplicada en la protección contra el rayo de aerogeneradores y aviones; los sistemas de seguimiento y aviso de tormentas; los ensayos de alta tensión en el laboratorio, etc. Una buena parte de la investigación del grupo se centra en la misión ASIM de la ESA, a la que contribuimos mediante el Laboratorio del Valle del Ebro, que contiene instalaciones de referencia en Europa, como la torre de medición de rayos del Niu de l’Àliga; la red de trazado de rayos 3D (lightning mapping array); cámaras de alta velocidad; interferómetros VHF;detectores de altas energías, y otros.
Our group's research tackles the field of atmospheric electricity and particularly the phenomenon of lightning. In our basic research we study the physics of lightning, transient luminous events (TLEs) in the upper atmosphere, terrestrial gamma-ray flashes (TGFs), high-energy emissions in lightning and electrical discharges, lightning activity in severe storms and electromagnetic fields produced by lightning. We also carry out applied research on lightning protection for wind turbines and aircraft, storm monitoring and warning systems, high-voltage laboratory tests, etc. Much of the Group's research focuses on the ESA's ASIM mission, to which we contribute via the Ebro Valley Laboratory’s benchmark European facilities, such as the lightning measurement tower in Niu de l’Àliga, a lightning mapping array, high-speed cameras, VHF interferometers and high energy detectors. Lightning physics and effects and atmospheric electricity processes. Lightning effects and protection on electrical systems, wind turbines and aircraft. Lightning location systems, observation and measurement of lightning parameters. Observation of mesospheric electrical discharges. High voltage test and research on the energetic processes of electrical sparks. Research on the protection of composite materials employed in aerospace and wind energy industry. Electromagnetic simulation and testing of complex structures.
