A video lecture titled, ‘Atmospheric radiation – Radiation laws’ from the e-learning course, ‘Introduction to Atmospheric Science’ developed by C Balaji, IIT Madras, for National Programme on Technology Enhanced Learning (NPTEL), India. This video lecture includes discussions on various aspects of radiation, atmospheric radiation and the radiation laws.
Students will be introduced to radiation, radiation laws and the concept of blackbodies. They will further learn about Earth’s energy balance and how to calculate surface temperatures using the Stefan-Boltzmann law. They will also learn about Wien’s displacement law, and Planck’s distribution.
A transcript of the lecture is also provided.
- Define ‘blackbody’.
- What are the features of ‘Planck’s distribution’?
- How can Stefan – Boltzmann law be used to calculate the surface temperature of planet earth?
