Análisis de la actividad de rayos y de tormentas relacionadas con la producción de rayos gamma terrestres
(Universitat Politècnica de Catalunya, 2015-03-05)
Doctoral thesis
Open AccessTerrestrial Gamma ray Flashes (TGFs) have been known since 20 years ago, but since the first moment of the discovery it was clear that they were related to lightning and thunderstorms. The latest studies revealed that TGFs ... -

Atmospheric boundary layer height disambiguation using synergistic remote sensing observations: case examples from VORTEX-SE
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2020)
Conference report
Open AccessSynergistic remote sensing of the atmosphere, combined with adaptive techniques, offers unprecedented opportunities to characterise the evolution of key atmospheric features such as the Atmospheric Boundary Layer (ABL). ... -
Characteristics of lightning flashes generating sprites above storms (i-DUST)
(EDP Sciences, 2016)
Conference report
Open AccessSprites are Transient Luminous Events (TLEs) that can extend vertically from 40 to 90 km and horizontally over several tens of km to form clusters of individual or multiple column or/and carrot-shaped luminous elements. ... -

Charge structure of two tropical thunderstorms in Colombia
(2019-04-23)
Article
Open AccessCharge structure derived from lightning leader development of tropical thunderstorms comprising equatorial latitudes of < ±10° has not been investigated yet. In this work, using a Lightning Mapping Array (LMA) installed ... -
Coastal wave storms: Observations and simulations in the NW Mediterranean
(Universitat Politècnica de Catalunya, 2009-06-03)
Master thesis
Open AccessThe importance of improving wind-wave predictions for the NW Mediterranean coastal region makes it necessary to perform a study in-depth of wave generation and propagation mechanisms under sharp spatial and temporal ... -

(2014)
Conference report
Open AccessRHESSI and AGILE TGFs distributions in the period 2009-2012 are compared. Analysis of differences in geographical, hourly, monthly distributions of the three main TGF production regions in Earth due to differences in ... -
Dancing sprites: detailed analysis of two case studies
(2017-03-27)
Article
Open AccessOn 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, ... -

High altitude leaders mapped by the Colombia lightning mapping array
(2016)
Conference report
Open AccessOn April 2015 a Lightning Mapping Array network (COL-LMA) was installed at the north of Colombia. This network provides 3D mapping of the development of lightning leaders. For the first time such network has been setup in ... -
How good are symmetric triangular synthetic storms to represent real events for coastal hazard modelling
(2020-08)
Article
Restricted access - publisher's policyCoastal risk assessments rely on proper quantification of storm-induced erosion and flooding, and often involve calculations via numerical models. When the real time-series data of a storm are not available as forcing ... -
