LRG - Lightning Research Group
La recerca del nostre grup és en l'Electricitat Atmosfèrica i especialment en el fenomen del llamp. A la recerca bàsica treballem en: l'estudi de la física del fenomen del llamp; els esdeveniments lluminosos a l'alta atmosfera TLE; les emissions terrestres d'alta energia TGF; les emissions d’altes energies en llamps i descàrregues elèctriques; l'activitat de llamps en tempestes severes; i els camps electromagnètics produïts per llamps. També realitzem recerca aplicada en: la protecció contra el llamp d’aerogeneradors i avions; sistemes de seguiment i avís de tempestes; assaigs d'alta tensió al laboratori; etc. Bona part de la recerca del grup es centra en la missió ASIM de l’ESA on hem establert el Laboratori natural de la Vall de l'Ebre amb les instal·lacions de referència a Europa com ara: la torre de mesura de llamps del Niu de l’Àliga; la xarxa de traçat de llamps 3D Lightning Mapping Array, càmeres d’alta velocitat, interferòmetres VHF, detectors d'altes energies; i altres.

High-resolution spectra of sprites and halos with GRASSP
(2017)
Text en actes de congrés
Accés obertThe first and simultaneous spectroscopic campaigns of TLEs were carried out in the mid 1990s [1, 2], soon after the discovery of TLEs in 1989 [3]. These initial campaigns provided preliminary results on the optical emissions ... -
Characteristics of lightning flashes generating dancing sprites above thunderstorms
(2017)
Comunicació de congrés
Accés obertDuring the night of October 29-30, 2013, a low-light video camera at Pic du Midi (2877 m) in the French Pyrénées, recorded TLEs above a very active storm over the Mediterranean Sea. The minimum cloud top temperature reached ... -

Accés obertA Stewart platform is a kind of parallel robot which can be used for a wide variety of technological and industrial applications. In this paper, a Stewart platform designed and assembled at the Universitat Polit`ecnica de ... -
Dancing sprites: detailed analysis of two case studies
(2017-03-27)
Article
Accés obertOn 29–30 October 2013, a low-light video camera installed at Pic du Midi (2877¿m), recorded transient luminous events above a very active storm over the Mediterranean Sea. The minimum cloud top temperature reached -73°C, ... -
Aliasing of the Schumann resonance background signal by sprite-associated Q-bursts
(2017-12)
Article
Accés restringit per política de l'editorialThe Earth's naturally occurring Schumann resonances (SR) are composed of a quasi-continuous background component and a larger-amplitude, short-duration transient component, otherwise called ‘Q-burst’ (Ogawa et al., 1967). ... -

Spatio-temporal dimension of lightning flashes based on three-dimensional Lightning Mapping Array
(2017-10-15)
Article
Accés obert3D mapping system like the LMA - Lightning Mapping Array - are a leap forward in lightning observation. LMA measurements has lead to an improvement on the analysis of the fine structure of lightning, allowing to characterize ... -
Characteristics of the 3 most common types of occupational accident in Spanish sub-surface and surface mining, from 2003–2008
(2012-04)
Article
Accés obertThe rate for work related accidents in Spanish mining has decreased during recent years. However, the incidence rate per 100,000 workers in the Spanish mining sector in 2007 was significantly higher than the ones reported ... -
Observations of the relationship between sprite morphology and in-cloud lightning processes
(2006-08-04)
Article
Accés obert[1] During a thunderstorm on 23 July 2003, 15 sprites were captured by a LLTV camera mounted at the observatory on Pic du Midi in the French Pyrénées. Simultaneous observations of cloud-to-ground (CG) and intracloud (IC) ...
