• Encouragements and acknowledgements
International Polar Year (IPY, Mar 2007 – Mar 2009)
• March 2007 – March 2009, Project Office in BAS (UK)
• Launched by ICSU and WMO
• Eight science themes (e.g. Ocean, Ice, Atmosphere, Space)
• Expressions of Interests (>1000) and core projects (>400)
• EoIs submitted in January 2005, final endorsements in November 2005
• IPY provides support for networking, core funding comes from national sources.
Heliosphere impact on geospace
• IPY core project (#63) conducted by ICESTAR, IHY (International Heliophysical Year) and 27 other consortia with scientists from 22 countries.
• Science about coupling phenomena affected by solar activity and cosmic background radiation
• Between the different atmospheric layers
• Between the magnetosphere and ionosphere
• Between the different hemispheres
• In addition
• Development of Virtual Observatories
• New instrumentation and technology
• http://www.space.fmi.fi/ipyid63
IPY project 63: Who are the others?
• Instrument networks (monitoring): EISCAT, SuperDARN, Auroral Optical Network, Riometers, Ionospheric tomography chains, GPS-receivers
• Groups who want to run multi-instrumental campaigns and desing or test new technology (e.g. long duration balloon flights, new radars)
• Groups who want to utilize the unique measurement conditions in the Antarctica
• Groups who want to test ”grazy” ideas
• Lead contacts: UK 6; US, Russia, Japan 4; Italy 3

Goals for this meeting• Identify the grand unified science goals
• Identify our resources: people, instrumentation, models and data analysis tools
• Set up routines for monitoring the outcome
• Boost up the usage of Virtual Observatories
• Discuss opportunities to get more money
• Get to know each other
IPY-IHY-ICESTAR networking
• Persons contacted:
• IHY CIP proposers
• ICESTAR Topical Action Group leaders
• IPY Expression of Interest Lead contacts
• The process will be continued..
SuperDARN Radars: Plasma convection
• Maps of the Super Dual Auroral Radar Network (SuperDARN) arrays over the Northern (left) and Southern (right) polar regions. The Antarctic map shows fields-of-view for existing (yellow) and planned (orange) radars.
Mesosphere and Lower Thermosphere Radars
Current Antarctic MLT Sites
South Pole, Scott Base, Davis, Syowa & Rothera
Current Arctic MLT Sites
Esrange, Andennes, Tromso, Svalbard, Dixon Island, Resolute Bay, Yellowknife, Barrow http://sisko.colorado.edu/TIMED
IPY Data Policy• ”Data should be carefully collected, freely accessible,
adequately preserved, and timely distributed”
• ”Data should be accompanied by a full set of metadata that completely describes the measurements”
• ”A legacy of versatile data systems”
• Solution: Virtual Observatories, one shopping site for observations from distributed sources
• Difference from Word Data Centers: VOs transfer data only upon user’s request.
• ICESTAR: GAIA and VGMO; Madrigal and SuperDARN, GPS and ionospheric tomography chains
How to get data providers motivated?• VO’s could apply for Digital Object Identification code,
c.f. AGU journals doi:10.1029/XXX
• Suggestion: DOI prefix: IPY, DOI suffix: VO
• Improvement to URLs: URLs change, DOIs persist
• Improvement to publications: Information behind DOIs can be updated easily
• Scientists using your data could easily refer to your DOI->User statistics for funding parties
• The drawback: Getting a DOI costs some real money… (member fee and annual fee)
IPY-4 versus IGY• Improvements since the IGY days:
• Long time series available
• Combined analysis of different data sets (ground-based and space-based)
• Data mining with machine vision methods
• Theoretical models help interpretation
• Advancements in the instrumentation
• From qualitative to quantitative descriptions
