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

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..

Optical Networks: Auroral precipitation, conductances

Magnetically conjugate regions

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.

Riometers: Energetic precipitation

Coordinates: Data base of the Lancaster University

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
