Introduction to Atmospheric and Space Sciences

Introduction to Atmospheric and Space Sciences. Instructor: Prof. Mv Sunil Krishna, Department of Physics, IIT Roorkee. This course introduces the basics of Earth's atmosphere to graduate and post-graduate students. It starts from the evolution of the atmosphere and gives understanding of various physical and chemical processes responsible for the observed changes we see in weather and climate. It gives a comprehensive understanding of the neutral atmosphere, ionosphere and various plasma processes. (from nptel.ac.in)
