During the Northern Hemisphere summer of 2003 a sprite observation campaign was conducted from Southern Europe and the magnetically conjugate region in South Africa. The campaign brought together a wide variety of instrumentation to investigate the effects of sprites on the mesosphere, and to search for signatures of the relativistic electron acceleration process in the magnetically conjugate hemisphere. Measurements in Europe included optical video imaging from a remote-controlled, semi-automatic camera system located at the Observatoire du Pic du Midi in the Pyre´ne´es mountains in Southern France, infrasound observations from France, and ULF-HF electromagnetic observations from a number of locations. The measurements in South Africa included observations of optical emissions and VLF electromagnetic waves. The campaign was successful, with more than 100 sprites observed during 10 storms. The paper will give an overview of the campaign and some results. They include: (1) the first clear identification of infrasound from sprites, allowing independent (of optical observations) estimates of the energy input to the mesosphere, (2) the first detection of sprites triggered by intra-cloud lightning, a result that underscores the need for considering the complete thunderstorm source field resulting from both cloud-to-ground discharges and the intra-cloud discharges feeding them, and (3) a clear one-to-one relationship with sprites and early VLF events, suggesting that VLF ground transmitter signals can be an important tool for estimating ionisation and relaxation of ionised structures in sprites. No signatures of relativistic electrons were identified during the campaign. r

“…Infrasound observations were made from Flers, France (Farges et al, 2005). ELF (extremely low frequency, 3 Hz − 3 kHz) observations in the 5 − 30 Hz range were performed at Nagycenk, Hungary, providing information about the CG lightning charge moments, that is, the amount of electric charge removed by the discharge multiplied by the altitude from which it was removed (e.g., see details in Sátori et al, 1996 andMarshall et al, 2005…”

First of all, I would like to express my gratitude to my supervisor, Christos Haldoupis, for his guidance with my thesis work during my three and a half years at the University of Crete. We shared many hours of stimulating discussions which have also provided me with new ways of looking at scientific problems. I am also very thankful for his hospitality and kindness which made my stay on Crete even more enjoyable. I thank to the Physics Department of the University of Crete and my professors for the graduate courses which enriched my knowledge, and also for generously placing at my disposal the facilities needed for my work. I also thank to the computer centre personnel who provided me with continuous help and support. My PhD studies were sponsored by the CAL (Coupling of Atmospheric Layers) network, under the European Union Research Training Network contract HPRN-CT-2002-00216. I wish to thankTorsten Neubert, the PI of the network for his scientific leadership in this project which benefited everyone, including myself. CAL provided me with the opportunity to obtain high quality research training and a PhD degree, while also having made my attendance of a number of memorable meetings and conferences possible. Working together with the CAL young scientists during the long sprite-watch nights and writing joint publications added a lot to my abilities to work as a member of a team. I wish to thank in particular to Oscar A. van der Velde for our inspiring discussions and collaboration which resulted in some joint publications. Umran S. Inan, our collaborator from Stanford University, advised me all along the way and provided me with lots of discussions which have enriched my knowledge significantly. Craig J.Rodger from the University of Otago has never gotten tired of helping me to improve my understanding of the field. János Lichtenberger from the Eötvös Loránd University clarified many of the technical issues behind VLF measurements to me and guided me in setting up the OmniPAL VLF receiver. David Nunn from the University of Southampton guided my efforts to model VLF scattering. Robert A. Marshall from Stanford University has never run out of patience to answer my numerous requests for help with our Stanford receiver and VLF data analysis. Tilmann Bösinger has helped me a lot with both scientific and personal matters, and I am greatly indebted to him for having made my attendance of the 2 nd VERSIM meeting in Sodankylä, Finland, possible. Sergei S. Shalimov provided guidance with some parts of my work and fruitful scientific advice. Many special thanks go to René J. Steiner who introduced me to emacs and L A T E X, saving me a huge amount of time and fuming when writing up my thesis.Last, but not least, I thank to my family for their love and support on which I could always count.
