  1. National Aeronautics and Space Administration Energy and the Atmosphere Dr. Lin H. Chambers, NASA Langley Research Center, Hampton, VA New Orleans, Oct. 29, 2010 www.nasa.gov

  2. Our Natural Place … in the Big Picture Mars Earth Venus Mercury Not to Scale Earth’s Energy Budget

  3. Our Natural Place … in the Big Picture “Too hot!” “Too cold!” Mars Ts= -113 to 0 C Earth Venus Ts=450 C! Mercury: Ts=425 C 425 C ~ 800 F Earth’s Energy Budget

  4. Our Natural Place … in the Big Picture Mars Ts= -113 to 0 C Earth: Ts= -18 C* Venus Ts=450 C! Mercury: Ts=425 C 425 C ~ 800 F *No atmosphere Earth’s Energy Budget

  5. Our Natural Place … for Life “Just right” Mars Ts= -113 to 0 C Earth: Ts= 15 C* Venus Ts=450 C! Mercury: Ts=425 C 425 C ~ 800 F *With atmosphere Earth’s Energy Budget

  6. What Determines a Planet’sTemperature? Earth’s Energy Budget

  7. The Energy Budget Earth’s Energy Budget

  8. The Energy Budget - An Analogy Winter Summer Earth’s Energy Budget

  9. The Energy Budget - V.2 Earth’s Energy Budget

  10. The Energy Budget - Location Top of Atmosphere (TOA) Earth’s Energy Budget

  11. The Energy Budget - Location Surface (SFC) Earth’s Energy Budget

  12. The Energy Budget – Direction Down Earth’s Energy Budget

  13. The Energy Budget – Direction Up Earth’s Energy Budget

  14. The Energy Budget - Wavelength Shortwave (SW) or Solar Shortwave (SW) or Solar Earth’s Energy Budget

  15. The Energy Budget - Wavelength Longwave (LW) Or Infrared (Heat) Earth’s Energy Budget

  16. The Final Frontier In atmosphere budget Earth’s Energy Budget

  30. How We Measure

  31. The CERES Instrument 3 telescopes • Shortwave (SW) • Total spectrum (TOT) • Window channel (LW)

  32. Satellites Carrying theCERES Instrument • TRMM Satellite launched 1997 • TERRA Satellite launched 1999 • Aqua Satellite launched 2002 • NPP (2011) • NPOESS (201?)

  33. First Year of CERES Data Earth’s Energy Budget

  34. Observe from anywhere The CERES S’COOL Project http://scool.larc.nasa.gov How we Validate • Lots of high tech methods, but also • Student involvement: Observe clouds at the time of the CERES satellite overpass Earth’s Energy Budget
