Vertical thermal structure of the atmosphere – vertical variation of pressure, temperature and density in the atmosphere; Major and Minor constituents of the earth’s atmosphere and their role in earth’s climate; Aerosols.
•    Thermal classification of atmospheric layers: troposphere, stratosphere, mesosphere, and thermosphere; Introduction to the structure of Earth’s ionosphere and magnetosphere.
•    Spectra of solar and terrestrial radiation; Absorption and scattering of solar and terrestrial radiation in the atmosphere; Radiation and energy budget of the earth-atmospheric system; Greenhouse effect.
•    Climate System – Roles of various components of the Earth System in determining Climate. Feedback processes in Climate System – concept of feedback, applications of feedback to the climate system.
•    Hydrological Cycle in the Earth System; Carbon Cycle in the Earth System; Oxygen in the Earth System
•    Climate Variability- Milankovich cycle, Internally generated climate variability, coupled climate variability, Anthropogenic forcing of climate change; El Nino Southern Oscillation.

Solid Earth Component
