A micro-lecture that describes the vibrational modes of polyatomic molecules, how these modes determine whether the molecules are IR inactive or IR active and explains why most IR active polyatomic gas molecules are greenhouse gases.
A reading that discusses how chemical bonds in molecules respond to incident IR light and absorb IR energy during certain modes of vibration. The reading includes discussions on the vibrational modes of water vapor and carbon dioxide (CO2) molecules and explains why these gases act as greenhouse gases.
A visualization to observe, understand, explore, and analyze the molecular structure of carbon compounds (CO2, CH4), the effect of electromagnetic radiation on these molecules, and the role of greenhouse gases in climate change.
A visualization and associated activity to explain how Planck’s Law can be used to plot blackbody curves of objects with different temperatures, the relationship between temperature and peak wavelengths in the electromagnetic spectrum, and the greenhouse effect of Earth’s atmosphere.
A model/simulator to learn about vertical energy (heat) transfer in the Earth’s system and planetary energy balance.
This video is an introductory lecture of the online E-course by Prof David Archer, a renowned Climate Scientist. Prof Archer introduces the concept of Green House effect and other anthropological activities through this video.
A reading to learn about the energy balance of planet Earth and to understand atmospheric warming by using a single-layer atmosphere model.
A model/simulator to understand the effect of greenhouse gases on outgoing energy flux, and to compare the absorption of infrared radiation by various greenhouse gases such as carbon dioxide (CO2), methane (CH4), and water vapor.
A visualization to learn about the infrared (IR) spectra of different greenhouse gases and the effect of greenhouse gases on the Earth’s climate.
