Introduction to Atmospheric Science

Introduction to Atmospheric Science. Instructor: Prof. C. Balaji, Department of Mechanical Engineering, IIT Madras. This course provides an introduction to atmospheric science which is concerned with the structure and evolution of planetary atmosphere and the phenomena associated with them. The course covers lessons in the Earth system, atmospheric thermodynamics, radiative transfer, atmospheric dynamics, atmospheric boundary layer, and climate dynamics. (from nptel.ac.in)
