• Space Missions
![Page 2: UAFs Contribute To Major Science Programs](https://reader034.fdocuments.net/reader034/viewer/2022051403/56816735550346895ddbe2a8/html5/thumbnails/2.jpg)
CEDAR New Dimensions Strategy
• CEDAR Strategic Plan• Overarching Problem Statement:
‘What are the geospace impacts on Earth’s habitability and the sustainability of technology-reliant societies?’
![Page 3: UAFs Contribute To Major Science Programs](https://reader034.fdocuments.net/reader034/viewer/2022051403/56816735550346895ddbe2a8/html5/thumbnails/3.jpg)
CEDAR New Dimensions
• Climate Change with the geospace system – Space climate– Geospace effects on climate
• Complexity in the geospace system– Nonlinear, complex system (e.g. space weather,
extreme events)
• Energy flow in the geospace system– Follow the energy– Propagation, Transformation, Manifestation
Contributions/input to the plan are very welcome!

CEDAR New Dimensions
• Themes are Global• Measurements are not…

Why is Antarctica different?
![Page 7: UAFs Contribute To Major Science Programs](https://reader034.fdocuments.net/reader034/viewer/2022051403/56816735550346895ddbe2a8/html5/thumbnails/7.jpg)
Pivotal Science with an Antarctic ISR
• Large scale interhemispheric asymmetry in magnetosphere-ionosphere coupling.
• Difference in interhemispheric potential• Interhemispheric asymmetry on intermediate and small
scales• Plasma sources for the magnetosphere• Interhemispheric asymmetry in the mesosphere and
thermosphereQuickTime™ and a
decompressorare needed to see this picture.

• Space Weather– Magnetosphere-Ionosphere coupling– Plasma source/Ion outflow– Coupling/non-coupling between scales
• Global climate change/disruption– Interhemispheric asymmetry in mesosphere and
thermosphere– Neutral dynamics
• Space Missions– Space weather– Global change…
Pivotal Science with an Antarctic ISR
So where does AMISR fit in?
![Page 9: UAFs Contribute To Major Science Programs](https://reader034.fdocuments.net/reader034/viewer/2022051403/56816735550346895ddbe2a8/html5/thumbnails/9.jpg)
AMISR Changes the Picture• ISRs have been considered in
Antarctica before• Structural size, heavy equipment,
complexity of O&M were significant issues
• AMISR reduces the issues to completely manageable sizes

RISR
![Page 13: UAFs Contribute To Major Science Programs](https://reader034.fdocuments.net/reader034/viewer/2022051403/56816735550346895ddbe2a8/html5/thumbnails/13.jpg)
Possible locations
![Page 14: UAFs Contribute To Major Science Programs](https://reader034.fdocuments.net/reader034/viewer/2022051403/56816735550346895ddbe2a8/html5/thumbnails/14.jpg)
• Polar Cap– Environment is characterized by open field-line geometry where the
Earth’s magnetic field connects into the interplanetary fields of the Sun and the Solar Wind.
– Small scale physics of field-line reconnection, viscous coupling between the solar wind and the magnetosphere, and the interchange of particles and energy between geo- and inter-planetary space.
• Auroral Zone– Propagation of particles and/or waves along flux tubes; inter-
hemispheric differences in substorm optical, magnetic, and riometer particle precipitation signatures; and substorm evolution in the deep tail
• Sub-Auroral Zone– Energy transport within the geospace system– Near auroral-zone observations also provide remote sensing of the
Earth’s radiation belts (approximately between L shells of 4 and 8).

McMurdo
• Polar cap location• Relative ease of logistics• Should be realized while RISR-N is still
in the northern polar cap• Solar max - polar cap, solar min - lower
latitudes
![Page 17: UAFs Contribute To Major Science Programs](https://reader034.fdocuments.net/reader034/viewer/2022051403/56816735550346895ddbe2a8/html5/thumbnails/17.jpg)
Additional sites/relocations
• Polar cap (McMurdo)• Cusp (Davis/Zhong Shan)• Auroral (Troll)• Sub-Auroral (Peninsula/Palmer)
Great opportunity for international collaboration….

• CEDAR new strategy– Geospace on a global scale– Systems approach to S-T
• Success and practicality of AMISR
So what could this look like?
![Page 25: UAFs Contribute To Major Science Programs](https://reader034.fdocuments.net/reader034/viewer/2022051403/56816735550346895ddbe2a8/html5/thumbnails/25.jpg)

Antarctic ISR - EISCAT 3D?
• Initiative of next generation EISCAT radar in mainland EUROPE - EISCAT 3D
• Possibility of upgraded Antarctic AMISR using EISCAT 3D ideas as part of the design
• Important step in international collaboration between US and EISCAT in Antarctica
![Page 27: UAFs Contribute To Major Science Programs](https://reader034.fdocuments.net/reader034/viewer/2022051403/56816735550346895ddbe2a8/html5/thumbnails/27.jpg)
Summary
• We have a critical need for understanding• We have the technology, expertise, and experience• We can exploit available capabilities to solve societally
important problems
• Also exploits OPP expertise and experience in Antarctica to complete northern hemisphere programs
• The time is now (but there’s lots to do for the 2nd site)One last idea…
