  1. Joris de Vroom (vroom@knmi.nl) Folkert Boersma (boersma@knmi.nl) www.knmi.nl/globe www.globe.gov The GLOBE Aerosol Monitoring project:experiences with undergraduates

  2. Content • The project • Aerosols • Method • Key issues • Results • Desert??

  3. The GLOBE project (1) • Within the framework of the GLOBE project (1995) • Global Learning and Observations to Benefit the Environment • GLOBE project: education by measuring environmental parameters (T, P, clouds, Aerosol etc.) • >100 countries, > 10.000 schools

  4. The GLOBE project (2)

  5. The GLOBE Aerosol Monitoring project • Undergraduate students (15-18 Y) measure Aerosol Optical Thickness (AOT) • Objectives: • Scientific: • Establish a school aerosol network • Perform actual satellite validation • Educational: • Education in atmospheric composition • Generate interest in beta sciences • Outreach: OMI and SCIAMACHY

  6. Aerosols (1)

  7. Aerosols (2) • Small particles in the air • Examples: • Soot • Dust • Sulphate • Sea salt • Vulcanic aerosol

  8. Aerosols (3)

  9. Aerosols (4) • Sources are both natural and antropogenic • Aerosols play an important role in climate change (direct and indirect effect)

  10. Aerosols (5)

  11. Method (1) • practical approach. • Undergraduate Students measure direct Sunlight(508 & 625 nm) with a GLOBE Sun photometer

  12. Method (2)

  13. Method (3) • Students also denote meta-data (P, T, clouds etc.) • The measurements (Voltage etc.) are reported on the internet to KNMI and to GLOBE database • Measurements are processed  AOT • Students can view AOT results at www.knmi.nl/globe

  14. Method (4) Students do measurement feedback KNMI (NL) Students report meas. on the internet GLOBE (US) database

  15. Method (5) www.knmi.nl/globe

  16. Method (6) www.knmi.nl/globe

  17. Method (7) www.knmi.nl/globe

  18. Summary • Undergraduate students (15-18) • Practical approach • AOT measurements • Report via internet to scientists • Scientists give feedback

  19. Key issues (1) Necessary conditions: • Motivated teacher • Quick feedback of results to students (website) Important for data quality: • Clear meta-data • Continuous data-stream

  20. Key issues (2) Possible problems: • Clouds / Contrails (meta-data) • Continuity of measurement series • # measuring days due to weather conditions (motivation)

  21. Results (1)

  22. Results (2) The Hague Amsterdam

  23. Conclusion • Network contains 17 schools • Students are actively involved in science • Encouraging validation results • Students can do it!! Important for the project: • Project integrated in lesson • Regular feedback • Teachers need to be committed

  24. Outlook • More schools • Development of lesson material • Achieve science goals: • Intra-pixel variability • Quantitative validation • ………
