  1. Presented by: Noreen Castellanos Netsay Ramos Instructor: Emily Chu Greenhouse Effect

  2. ROY G. BIV • List the abbreviated colors • Visible spectrum is the colors your eye can detect • Red is the first color on the left, with a large wavelength and a low frequency • Violet is opposite red

  3. http://earthguide.ucsd.edu/earthguide/diagrams/greenhouse/ Animation • Here is an animation to help you understand what really happens.

  4. Blackbody effect is both absorption and the resulting emission. The black body's temperature affects the intensity of emission.Earth then releases infrared rays back into space. Black Body Effect 1. Earth absorbs most radiation.Its temperature is based on the amount of radiation it absorbs.

  5. Albedo The reflectivity of any substance the albedo.The albedo for Earth is roughly about 0.28; 0.28 is a ratio, has no units. Albedo reflects the sun's light back to the atmosphere and most of the time back to space.

  6. Greenhouse Gases Although many people think that the Greenhouse effect is harming the environment, it is actually essential for the survival of life on Earth. The Greenhouse effect keeps water at a liquid temperature and maintains the Earth at a warm and stable temperature for its inhabitants.

  7. Experiment • Measure the absorbance of GHG • FTIR Spectrometer • SO2, CH4, and CF3CH2F

  8. Greenhouse Warming Potential • GWP is how much these gases can heat up the Earth. • The GWP over 100 years for SO2 is .019891 • For CH4, the GWP is 7.24002 • The GWP for CF3CH2F is 466.0454

  9. Carbon Dioxide Stretches • Symmetric, Asymmetric, and bend. • Asymmetric stretches are IR active.

  10. Kyoto Protocol The Kyoto Protocol was made in Japan, in 1997. It is an agreement signed by many countries and industrialized nations to commit to cutting Greenhouse gasses to 5% below the 1990 levels.
