1. PLANS FOR THE INTERNATIONAL HELIOPHYSICAL YEAR J. Davila, B. Thompson, N. Gopalswamy NASA-GSFC October 14, 2004

2. IHY (http://ihy.gsfc.nasa.gov)2 Why IHY? The Historical Perspective First International Polar Year –January 1875 at the Academy of Sciences in Vienna Carl Weyprecht suggested a coordinated study of the north polar region –Polar meteorological and magnetic observations commenced on Aug 1, 1882 and concluded Sep 1, 1883 Second International Polar Year –Scientific activities were significantly limited by the world-wide economic depression –Polar meteorological and magnetic observations to be made in 1932-1933, fifty years after the first IPY The logical next step is to extend global studies into the Heliosphere to incorporate the drivers of Geophysical change into the global system-The IHY. International Geophysical Year –In 1957 the IGY involved about 60,000 scientists from 66 nations –To obtain simultaneous, global observations on Earth and in space

3. IHY (http://ihy.gsfc.nasa.gov)3 Evolution of System Studies 1957193320071883 TIME Size Scale Studied IPY-1 IPY-2 IGY IHY

4. IHY (http://ihy.gsfc.nasa.gov)4 Advances During Previous International Years IPY 1 –Auroral oval structure and dynamics –Currents flowing in the upper atmosphere produce magnetic perturbations on the ground –Currents flow between upper atmosphere and space IPY 2 –International polar observing network –New instrumentation (radiosondes and ionosondes) –Rapid run magnetometers –Simultaneous measurements at multiple stations –Global current pattern for specific magnetic disturbance (magnetic bays) IGY –Interhemispheric network of polar stations –New instrumentation (all-sky cameras, satellites) –Major discovery (radiation belts) –New concepts (the magnetosphere, substorms) –Exploration of space –Global 3D synoptic data –Evidence of time-dependent global dynamics Lapland, 1882

5. IHY (http://ihy.gsfc.nasa.gov)5 IHY Scientific Goals Provide benchmark measurements of the response of the magnetosphere, the ionosphere, the lower atmosphere and Earth surface to identify global processes and drivers which affect the terrestrial environment and climate Global study of the Sun-heliosphere system outward to the heliopause to understand the external, and historic drivers of geophysical change Foster international scientific cooperation in the study of Heliophysical phenomena now and in the future To communicate the unique scientific results of the IHY to the interested scientific community and to the general public

6. IHY (http://ihy.gsfc.nasa.gov)6 Why Now? A large armada of existing or planned spacecraft are in place to provide the most comprehensive global measurements of the sun- earth interplanetary system yet obtained Earth based observatories can provide measurements of terrestrial effects at the poles and elsewhere International collaboration is easier today than in previous international years with abundant and cheap electronic communication available No single country has sufficient resources to obtain all required observations The time is ripe for IHY global studies.

7. IHY (http://ihy.gsfc.nasa.gov)7 What is the Opportunity? Similar physical processes are evident in vastly different environments True-color image of Earths aurora taken from Space Shuttle Jupiters aurora imaged with HST Aurora at Saturns poles Cross-cutting solar system science

8. IHY (http://ihy.gsfc.nasa.gov)8 Cross-Cutting IHY Approach Observa- tional campaigns are organized for various phenomena Scientific results organized by physical process

9. IHY (http://ihy.gsfc.nasa.gov)9 General Benefits of the IHY The IHY will help us develop a deeper understanding of physical processes through a program of comparative study throughout the solar system. The IHY will further the study of energetic events in the solar system, paving the way for safe travel to the Moon and planets in the future. The IHY 2007 will serve to inspire the next generation of space physicists, as the IGY 1957 inspired us. The IHY will help maintain US leadership in space science.

10. IHY (http://ihy.gsfc.nasa.gov)10 Benefits to NASA Provides a community consensus structure to unite Earth and Space Science into the new field of helioPHYSICS. A good fit to the new Exploration Initiative organizational structure Broadens the use of space data by making data available, and involving new science groups while leveraging data analysis funds Provides National and World-Wide public visibility for NASA programs at all levels Pathfinder for ILWS science program, with high- priority concensus science objectives identified by International Teams

12. IHY (http://ihy.gsfc.nasa.gov)12 US Planning Workshop Sac Peak, NM 22-24 April, 2004 Objective – Begin to organize the scientific program for the IHY in the US science community Scientific organizers -- Nancy Crooker, and Dan Baker (Co-Chairs), Charles Jackman, Chuck Smith, Eberhard Mobius, and David Webb. K.S. Balasubramaniam and Alexi Pevtsov were Local Organizers. Four Working Groups Formed – –Climate and Earth Atmosphere (WG Leaders: Mark Baldwin and Rolando Garcia) –Magnetospheres and Ionospheres (WG Leaders: Howard Singer and Jan Soika) –Heliosphere and Solar Wind (WG Leaders: Justin Kasper and Eberhard Mobius) –Solar Drivers (WG Leaders: Terry Forbes and Sarah Gibson). Workshop talks and working group summaries are available at website http://www.nso.edu/general/workshops/ihy2004 http://www.nso.edu/general/workshops/ihy2004 IHY U.S. Community Science Workshop being planned in early 2005 in Boulder CO, International workshop will be held in July 2005 in Toulouse, France

13. IHY (http://ihy.gsfc.nasa.gov)13 Recent Progress Developed a schedule of activities and are making progress towards finalizing research plans for 2007 The International Steering Committee has been established Coordination with the UNBSS program continues. We will focus on partnerships with developing nations to establish distributed instrument networks, and we are exploring how to do it with help from UNBSS. Planning workshop in October at GSFC to discuss coordination. A larger meeting with UNBSS is scheduled for November in UAE Science Coordination Database has been established and is being populated, Campaign Coordination Database in development http://ihy.gsfc.nasa.gov/ IHY events and activities at scores of international meetings and symposia IGY Historical activities underway in partnership with the AGU History Committee, eGY and the AIPs Center for History of Physics
