IHY/ISWI Helps Facilitate NASA’s Leadership in International Space Science
• Provides unique science for geospace, heliosphere, and solar physics• Provides inter-agency focus for international space weather development• Supports NASA’s international activities• Leverages foreign science budgets to develop instruments to provide the
unique space weather related data that we need– More than 750 operating instruments in more than 100 countries– 15 instrument arrays donated by 7 countries– 7 UNBSS Workshops organized in 7 countries– 12 Space Science schools– 5 instrument specific training schools
• Developing new data sources for space weather forecasting and nowcasting• Establishes new university based space research groups in non-traditional
countries• Provides new opportunities for graduate research in space physics at BSc,
MSc, and PhD levels• Engages the public (100,000s) in space science outreach worldwide
IHY/ISWI Organization
• Primarily a collaboration between– NASA– United Nations Office of Outer Space Affairs
• Established by UN General Assembly resolution in 2005, and 2009
• Supported by the US Department of State
ISWI Objectives • Develop the scientific insight necessary to understand the science, and to
reconstruct and forecast near-Earth space weather – Instrumentation
• Expand and continue deployment of new and existing instrument arrays
– Data analysis • Expand data analysis effort for instrument arrays and existing data bases
– Coordinate data products to provide input for physical modeling• Input instrument array data into physical models of heliospheric processes• Develop data products that reconstruct past conditions in order to facilitate assessment of problems
attributed to space weather effects
– Coordinate data products to allow predictive relationships to be developed• Develop data products to allow predictive relationships that enable the forecasting of Space Weather to be
established• Develop data products that can easily be assimilated into real-time or near real-time predictive models
• Education, Training, and Public Outreach– University and Graduate Schools
• Encourage and support space science courses and curricula in Universities that provide instrument support
– Public Outreach• Develop public outreach materials unique to the ISWI, and coordinate the distribution

ISWI Participation (Jan 2012)
– 14 Distributed instrument teams observatory program– ~1000 participating locations– More than 100 Countries participating
Principles of the ISWI Instrument Program
• The lead scientist or principle investigator funded by his/her country provides instrumentation (or fabrication plans) and data distribution service
• The host country provides the workforce, facilities, and operational support typically at a local university or research institute.
• Host scientists become part of science team• All data and data analysis activity is shared • All scientists participate in publications and
scientific meetings where possible

Scientific Benefits: Why do this?
• By observing in new geographical regions, a more global picture of Earth’s response to solar wind inputs can be obtained
• Longitude coverage, 24/7 solar observing in radio and H-alpha, satellite collaboration (C/NOFFS, THEMIS)
• Arrays provide 3D information that can be used in tomographic reconstructions
• Long term these networks will provide real-time data valuable for forecasting and nowcasting
• Modeling improvements will allow better exploitation of existing data sets
