    Las actividades mineras son una de las industrias de mayor riesgo que exponen a los a sus trabajadores a un alto nivel de riesgo de salud y seguridad en el trabajo. El objetivo de este estudio fue evaluar durante un ...
  • High spectral resolution spectroscopy of sprites: A natural probe of the mesosphere 

    Gordillo Vázquez, Francisco; Passas, Maria; Luque, Alejandro; Sánchez, Justo; Van der Velde, Oscar Arnoud; Montañá Puig, Juan (2018-02-06)
    Article
    Open Access
    We present the first high spectral resolution (0.24 nm) spectra of sprites. These spectra were recorded in Europe in the summers and falls of 2015 and 2016 and during January 2017. The use of high-spectral resolution has ...
  • Dancing sprites: detailed analysis of two case studies 

    Soula, Serge; Mlynarczyk, Janusz; Fullekrug, Martin; Pineda Rüegg, Nicolau; Georgis, J.-F.; Van der Velde, Oscar Arnoud; Montañá Puig, Juan; Fabró Tàpia, Ferran (2017-03-27)
