Presentation Transcript

  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

  17. The Energy Budget - Data http://mynasadata.larc.nasa.gov Click Data Access Choose Live Access Server Choose Data Parameter Earth’s Energy Budget

  18. The Energy Budget - Data Earth’s Energy Budget

  19. TOA Shortwave Down What variables affect this? Earth’s Energy Budget

  20. TOA Shortwave Down Earth’s Energy Budget

  21. Surface Shortwave Down What variables affect this? Earth’s Energy Budget

  22. Surface Shortwave Down Earth’s Energy Budget

  23. Surface Shortwave Up What variables affect this? Earth’s Energy Budget

  24. Surface Shortwave Up Earth’s Energy Budget

  25. Surface Shortwave Up Earth’s Energy Budget

  26. Surface Longwave Up What variables affect this? Earth’s Energy Budget

  27. Surface Longwave Up Earth’s Energy Budget

  28. TOA Longwave Up What variables affect this? Earth’s Energy Budget

  29. TOA Longwave Up 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
