Thompson NASA GSFC Greenbelt MD 20771 What is IHY? ● An international program to expand the famous IGY 1957 concept to a much larger realm – the entire solar system up to the ISM boundary - in a unique way ● IGY reached to the frontiers of geophysical research in 1957 ● IHY will reach to the frontiers of heliophysical research focusing on universal physical processes and connective phenomena ● Heliophysical: encompasses solar-planetary physics to heliosphere-ISM interaction ● Grass-roots organization with a science focus and international cooperation

2. http://ihy.gsfc.nasa.gov Gopalswamy 26-29 Oct 2004, Kiyosato, Japan2 Why IHY? The Historical Perspective First International Polar Year (1882-1983) –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(1932-1933) –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 (1957-1958) –In 1957 the IGY involved about 60,000 scientists from 66 nations –To obtain simultaneous, global observations on Earth and in space

3. http://ihy.gsfc.nasa.gov Gopalswamy 26-29 Oct 2004, Kiyosato, Japan3 The original IGY encompassed all of the geophysical domains from oceans to atmospheres. After the IGY the separate fields dispersed and evolved into large communities. Now it is the 50th anniversary of the original IGY and this has caused all of these disciplines to re-aggregate and recreate the conditions which fostered the successful IGY – Towards an IHY.

4. http://ihy.gsfc.nasa.gov Gopalswamy 26-29 Oct 2004, Kiyosato, Japan4 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 IHY will build on this heritage Lapland, 1882

5. http://ihy.gsfc.nasa.gov Gopalswamy 26-29 Oct 2004, Kiyosato, Japan5 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. http://ihy.gsfc.nasa.gov Gopalswamy 26-29 Oct 2004, Kiyosato, Japan6 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.

9. http://ihy.gsfc.nasa.gov Gopalswamy 26-29 Oct 2004, Kiyosato, Japan9 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 and explorers, as the IGY 1957 inspired us.

10. http://ihy.gsfc.nasa.gov Gopalswamy 26-29 Oct 2004, Kiyosato, Japan10 Benefits to Space Agencies Provides a community consensus structure to unite Earth and Space Science into the new field of “helioPHYSICS”. Broadens the use of space data by making data available, and involving new science groups while leveraging data analysis funds Pathfinder for ILWS science program, with high- priority consensus science objectives identified by International Teams
