Unifying Theme

• 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.
• As our contribution to IHY, we propose to
  implement two major thrusts utilizing theory,
  observations and modeling
• End-to-end solar terrestrial system studies
• Comparative A-I-M systems

4
Science Thrusts with Examples

• End-to-end Solar-Terrestrial System Studies
  Modeling and Observations
• A Storm time response of the inner magnetosphere
  and ionosphere-thermosphere
• B Real-time global ionosphere
• C Sources of variability of the geomagnetically
  undisturbed atmosphere and ionosphere
• D Small-scale structures

5
Science Thrusts with Examples

• Comparative A-I-M Systems
• A Comparative studies of auroral dynamics on
  Earth, Jupiter and Saturn
• B Comparative studies of storms and substorms at
  different planets
• C Comparative studies of the radiation
  environment at different planets

End-to-end Solar-Terrestrial System Studies
Modeling and Observations

• Title Real-time global ionosphere
• Campaign leader Tim Fuller-Rowell
• Science question/goal Characterizing the global
  ionospheric variability as a function of season
  and geomagnetic activity
• Whats unique for IHY
• a. Interdisciplinary (coupling with lower
  atmosphere, solar radiation and solar
  electrodynamics)
• b. International (data contributions from many
  countries)
• c. Global (big picture ideas) - global
  characteristics with high-fidelity
• d. Discovery potential - longitudinal dependence
  in structures during varied external conditions
• Key instrumentation and data Global network of
  GPS, COSMIC
• Models Test existing numerical models including
  data assimilation
• Key proposals -Providing GPS systems to
  developing countries in key gaps
• Collaborations - CAWSES, VxOs, eGY,
• Workshops/collaborations Topical electronic
  workshops
• Educational opportunities Involving
  multi-national real-time effort with possible
  school programs

Comparative A-I-M Systems

• Title Comparative studies of auroral dynamics on
  Earth, Jupiter and Saturn
• Campaign leader Recommendations John Clarke/Fran
  Bagenal
• Science question/goal Understand the
  similarities and differences of physical
  processes creating aurora on different planetary
  systems
• Whats unique for IHY
• a. Interdisciplinary
• b. International
• c. Global (big picture ideas)
• d. Discovery potential
• Key instrumentation and data Cassini, JMEX,
• Models Test existing numerical models
• Key proposals - HST time

• Workshops/collaborations Topical electronic
  workshops
• Educational opportunities Similarities and
  difference between our planet and others in the
  solar system

9
Legacy Potential Examples

• Elevation of the role of modeling into a
  complementary research tool (maturing of modeling
  techniques including data assimilation)
• Furthering the establishment of comparative A-I-M
  systems as a discipline
• Utilizing eGY efforts to provide enhanced
  capabilities during the IHY and for future
  science endeavors
• Creating new connectivity in science cooperation
• Producing a comprehensive database which can be
  mined for future scientific discoveries
