1 Chapter 1 – Sun and Solar Radiation – Sun provides the energy for producing the ionosphere. Basic facts of the sun and solar system; solar structure; solar electromagnetic radiation, gamma rays, X-rays, EUV, UV, visible, infrared and radio waves; optical depth; energetic particle radiation; differential rotation; sunspots; solar activity and solar cycle; butterfly diagram; interplanetary magnetic field (IMF); solar wind; solar flares and coronal mass ejections (CMEs); heliosphere; non-solar energy sources, galactic cosmic rays, star light. 2 Chapter 1 3 Chapter 1 4 Chapter 1 5 Chapter 2 – Geomagnetic field – Geomagnetic field holds the plasma around the earth; it also controls the dynamics of the ionosphere (especially the topside), plasmasphere and magnetosphere. Basis of magnetic field; magnetic field of planets; geomagnetic field components; field line geometry, parameters of magnetic field; geomagnetic anomalies; magnetosphere; motion of charged particles in magnetic field, magnetic invariants, whistlers; magnetic reconnection and entry of solar wind; radiation belts; ring current; geomagnetic variations; geomagnetic storms; geomagnetic indices. 6 Chapter 2 7 Chapter 2 8 Chapter 2 9 Chapter 3 – Neutral atmosphere – The ionosphere (and hence plasmasphere and magnetosphere) are produced from the neutral atmosphere by solar radiation. Atmospheric structure and related topics, ozone layer, green-house effect, excess green-house effect and global warming, mesospheric and thermospheric cooling, exosphere, equation of state and equations of motion – continuity, momentum and energy equations, scale height and geopotential height; thermospheric circulation and neutral winds, effective magnetic meridional wind, modification of thermospheric circulation during geomagnetic storms; diffusion of neutrals; effect of winds on neutral composition; thermospheric variations; atmospheric tides, surges and planetary and gravity waves, Brunt-Vaisala frequency; travelling atmospheric disturbances (TADs). 10 Chapter 3 11 Chapter 3 12 Chapter 3 13 Chapter 4 – Ionosphere – Ionosphere has been studied for its advantages in groundbased HF communication and to find remedies for its disadvantages in all branches of telecommunication and navigation. Ionosphere of planets (comparison); Earth’s ionosphere; structure of ionosphere; ionospheric regions and layers; basic theory of ionosphere, production, chemical loss, transport, diffusion; formation of ionospheric regions and layers; ionospheric electric fields and currents, ionospheric dynamo, ionospheric conductivities, equatorial and auroral electrojets; dynamics and electrodynamics of the equatorial zone; equatorial ionization anomaly; equatorial plasma irregularities, spread F, plasma bubbles; electrodynamics of mid latitude ionosphere; waves and instabilities at mid latitude, LSTIDs, MSTIDs; dynamics and electrodynamics of mesosphere; high latitude ionosphere; effects of electric fields and neutral winds, ionospheric storms; global electric circuit and climate change. 14 Chapter 4 15 Chapter 4 16 Chapter 4 17 TBD 18 TBD
