Introduction,violet and a stream of particles of a wide spectrum of energies, from the solar cosmic rays (.~ 1 GeV) to sub-relativistic protons of energies between 1–1000 MeV that spiral along the Earth’s magnetic field lines into the polar regions within some 80 min to 4 h, down to the slower energy cloud of io

Description of SID Techniques and Observations,olar and ionospheric observatories, and those that are extremely complex and sophisticated facilities, available only to a few stations in the world. In the first category we have the SEA, SES/ SFA, SPA, SCNA, SFD and the satellite radio beacon method; in the second category, use is made of cross-mo

SID Phenomenology,of the SID event and the solar ionizing radiations have been examined by many authors. Much of the early works relating to the statistical characteristics of the SIDs concerned the use of Hα emissions in the absence of information of X-ray fluxes. Amongst the major works in this line are the work of

Development of Electron Density Profiles from Synoptic SIDs,use of wave interaction technique as in Penn State, partial reflection as in Ottawa, incoherent scatter and rocket soundings, (discussed in Chapter 2 and in some of the later chapters), these are necessarily limited. Consequently, there have been several attempts to use some of the more conventional

In contrast, there is extensive theoretical literature on comparing the performance of different pollution control instruments (for example, Baumol and Oates, 1988; Tietenberg 1990). In general, the debate has remained largely on the theoretical lev
