• Science Program “Expressions of Interest”– Over 1000, grouped into ~50 clusters, covering all areas of polar

science

• Heliosphere Impact on Geospace– One of the core projects of the fourth International Polar Year

program which will take place during March 2007 - March 2009.

• Project (IPY ID# 63) – Run by a federation of 29 international research groups from which

the ICESTAR and IHY communities will carry management responsibilty and will serve as the contact point towards the IPY Project Office.

IPY core project 63: Heliosphere impact on geospace

Heliosphere impact on geospace• Science: coupling of solar activity to Earth, effects:

– Between the different atmospheric layers – Between the magnetosphere and ionosphere– Between the different hemispheres

• In addition– Development of Virtual Observatories– New instrumentation and technology

• ICESTAR (2005-2009) Sponsored by SCAR– Project Office in Siena College (US)

• IHY (2007-2008) Endorsed e.g. by COSPAR, IUGG, NASA, and UN – Project Office in NASA/GSFC (USA)– Coordinated Investigation Programmes

Interhemispheric Conjugacy Effects in Solar-Terrestrial and Aeronomy Research

TAG-A: High-latitude auroral and ionospheric electrodynamics for quiet, moderate, and disturbed conditions in near-Earth space, and its regional differences and commonalities over the Arctic and Antarctic.

TAG-B: Geomagnetic (interhemispheric) conjugacy between the magnetosphere and both the Northern and Southern polar ionospheres during geomagnetic storms and substorms.

TAG-C: Coupling between the polar ionosphere and neutral atmosphere from the ‘bottom-to-top’ and the global electric circuit.

TAG-D: Virtual Arctic and Antarctic Geospace Observatories Network – a World Wide Web portal for the ICESTAR programme and SCAR’s SSG/PS.
