Acknowledgments

I wish to extend my warmest thanks to everyone who has in any way helped me with preparing and nishing this work and encouraged me along the way. I want to thank, rst of all, Dr. Jean-André Sauvaud from C.E.S.R., Toulouse, France, for providing me with opportunity to learn from him, and for oering me an access to the Interball ELECTRON data. My thesis adviser, Dr. Barbara Popielawska, for her helpful comments and big patience, when I was extending my deadline. I have held helpful discussions on the magnetospheric physics with Christian Jacquey from C.E.S.R., Toulouse and with Ela Wodnicka, SRC Warszawa. I am also very thankful to the whole group working, under guidance of J.-A. Sauvaud, on the ELECTRON experiment. Thanks also for the data processing to J. Durand (CNES, Toulouse) and E. Penou (C.E.S.R.). Dr. S. Romanov (SRI, Moscow, Russia) for the magnetic data- without the MIF-M instrument I would certainly have nothing to do. Dr. Józef Juchniewicz, Space Research Center, Warszawa for various kinds of support and Dr. Lech Kru±, System Research Institute PAS and Hewlett-Packard Education group in Warszawa for the opportunities to nd the additional source of nances. This work would not even start without the geophysical data I was using to support the observations from Interball.
The list of the institutes and of the individuals I wish to acknowledge is put below. The list of individuals, that I wish to acknowledge is very long; I keep it in my heart and in memory, often accompanied with love. Of course, colleagues from the laboratories in Toulouse and in Warszawa, but also friends, who come from backgrounds other than physics: Majka Shephard has helped me with some English (but still all the errors being my fault), Piotr Malec, Anka Salwa, Ula Styczek, have oered me their time and friendship and with Krysia Hulewicz we have talking a lot on energy. There are two special ladies I want to thank, keeping them in my memory and in my heart: Ula Orªowska and Marta Wachowicz. I also thank my Mother and my Brother for everything. I wish also to thank His Holiness XIV Dalai Lama of Tibet for the sense of support when I was working upon my thesis, and to wish Him all the best. Similarly, I keep warm thougths for Pope John Paul II for the lessons He gave us in His last days.
Finally, I want to acknowledge: Prof G. Parks for the data from WIND; Los Alamos National Laboratory (Dr. R. Belian) for the SOPA instrument data; Dr. Partick Newell at JHU APL for the usefull comments on the DMSP data. Canadian Space Agency for the magnetic and the optical data from CANOPUS chain of observatories (especially Dr. Fokke Creutzberg for the usefull and encouraging comments); Danish Meteorological Institute (in particular Dr. J. Watermann) and Space Physics Research Laboratory at the University of Michigan (Dr. R. Clauer) for the magnetic data from Greenland; Prof. K. Yumoto from STEL, Nagoya, Japan, for the magnetic data from MM210 magnetometer chain; National Institute for Polar Research, Japan (Dr. Akira Kadokura) for the magnetic data from Iceland and Syowa station; Dr. J.J.Schott from EOST, Université de Strasbourg, France, for the magnetic data from Port Aux Francais; the institutes who maintain the IMAGE network for the magnetic data; SAMNET, the PPARC facility deployed by the University of York UK for the magnetic data. I also would like to thank everyone providing the Internet global data services, in particular World Data Centers, NSSDC, SPIDR.
