  1. International Arctic Systems for Observing the Atmosphere (IASOA) for IPY 2007 and Comparison to the Ancestor Program of Coordinated Meteorological Measurements in IPY 1882

  3. Elements of IASOAInternational Arctic Systems for Observing the Atmosphere • Develop intensive International Arctic atmospheric observatories • Enhance atmospheric networks (e.g. BSRN, GAW, CRN, Aeronet, UVnet, MPLNet) • Integrate the atmosphere activities with hydrology, land, biological, oceanography, and cryosphere studies Partner Countries Canada, Finland, Norway, Russia, Denmark, China, Germany, Japan Sweden, United States, Italy

  4. Rational for Intensive Atmospheric Observatories To understand the Arctic atmosphere it is necessary to have detailed measurements of clouds, aerosols, radiation and surface fluxes. Clouds in the Arctic have been shown in a number of studies to have a major influence on surface radiation budgets and resulting surface temperatures, ice ablation/melt rates, and the onset of the annual snow melt season. Aerosols contribute to balances in the Arctic atmosphere by direct forcing and also by indirect cloud-aerosol effects. The emphasis is on taking measurements that contribute to understanding WHY climate is changing and not just HOW climate is changing. There is a special emphasis on untangling natural and anthropogenic influences, through process studies, satellite validation and model support.

  5. C. Weyprecht 1838-1881 The inspiration behind the first IPY FRANZ JOSEF LAND Carl Weyprecht and the 2nd Austro-Hungarian Polar Expedition (1872-1874) [Thousands of observations] only furnish us with a picture of the extreme effectsof the forces of Nature in the Arctic regions, but leave us completely in the dark with respect to their causes.

  13. Working Conditions have improved Since 1882!

  14. Instruments Radiometer P-AERI Cloud Radar HSRL (Lidar)

  15. Radiation Sensors Instruments Aerosol Samplers Mcropulse Lidar

  16. DATA

  17. Now we have better Instruments and methods For data archival

  18. The first IPY was a successful example of international scientific cooperation, but coordinated observations were not synthesized for 125 years!!! (Wood and Overland, 2006: Climate Lessons from the First International Polar Year, Bull. Amer. Meteor. Soc., Vol. 87, 1685-1697 IASOA should be more timely with understanding and utilizing data but it is still a very difficult problem

  19. Satellite Validation Nine-year comparison of monthly cloud fractions form surface, TOVS and AVHRR on NOAA satellites And MODIS on NASA satellites over Barrow, Alaska Detailed resolved cloud microphysics/optical properties Aerosol Cloud Interactions The Science Cloud Forcing of Surface Radiation Budgets

  20. Changes in sea ice cover Change in planetary albedo Melting permafrost release of greenhouse sequestered gases Relating results to climate issues Melting Greenland ice sheet – Rises in sea level

  21. IASOA is an invitation to all nations form a partnership to understand Arctic climate change
