We announce one PhD position under the supervision of the TRansient Plasmas in Planetary Atmospheres (TRAPPA) group (www.trappa.iaa.es) at the IAA - CSIC (www.iaa.es) in Granada within the context of the recently granted European Innovative Training Network “Science And INnovation with Thunderstorms” (SAINT) with 15 PhD students working in 10 academic institutions and collaborating with 9 companies. Collaboration within the network is strongly encouraged.

All nodes of the SAINT network participate in the training, feeding upon collaborations through the network. The position includes short stays in some of the world leading research centers within the network. Yearly meetings (summer and winter schools) of the complete network are foreseen.
PROJECT DESCRIPTION

The PhD project focuses on exploiting the scientific capabilities of our newly designed and recently built GrAnada LIghtning Ultrafast Spectrograph (GALIUS) in combination with the modeling of lightning dynamics. GALIUS is a portable, high spectral resolution imaging spectrograph that achieves unprecedented high speeds designed to work in the ultraviolet and visible spectral ranges. The PhD project aims at determining key spectral properties (electron density and temperature, electric current electric field, ...) of the different temporal phases (streamers, leaders, return stroke and arcs) of lightning in order to understand lightning dynamics and the chemical influence of lightning in the atmosphere. Thus, the project also involves the use and/or development of lightning leader models to compute the production of nitrogen oxides (NOx) and other chemical species (ozone, ...) in lightning processes using inputs from the spectral characterization of lightning. A number of spectroscopic + imaging campaigns will be undertaken in high-voltage facilities (where lightnings are mimicked) and different natural locations (for natural and/or triggerd lightning) in coordination with colleagues of collaborating groups.
