CEDAR Strategic Planning for the Next Decade

Jeff Thayer, CSSC Chair

Aerospace Engineering Sciences University of Colorado

CEDAR 2009 Workshop - Strategic Plan Presentation (revised)

Strategic Planning Forum

Motivation for a CEDAR Strategic Plan

  • CEDAR Phase III document is 12 years old
  • Research landscape is rapidly evolving
  • Initiatives are pushing the research and resource envelop of CEDAR
  • CEDAR needs to be better poised to contribute to high-priority, agency-wide research programs
  • CEDAR has icon status as the preeminent aeronomic body and is the right group to push concept forward

Benefits of the Strategic Plan

  • Unifies the Aeronomic field
  • Demands stronger collaboration with other research areas, such as lower atmosphere and magnetosphere
  • Explores transformational research
  • Defines resource needs
  • Responds to the new research landscape
  • Provides a platform from which new initiatives can build

Hour Glass Concept

  • Limited amount of SAND
  • Reformulate Problem Statement and Approach
  • Add more SAND (i.e ideas)

Strategy for a New Dimension (SAND) of CEDAR

Overarching Problem Statement: What are the geospace impacts on Earth\’s habitability and sustainability of technology-reliant societies?

"Man must rise above the Earth – to the top of the atmosphere and beyond – for only thus will he fully understand the world in which he lives.” Socrates

SAND Themes

Climate Change with the geospace system (mutual interaction)

Space climate
Geospace effects on climate

Complexity in the geospace system

Nonlinear, complex system (e.g. space weather, extreme events

Follow the energy

Propagation, Transformation, Manifestation=====

SAND Fundamental Processes

Forcing, Response and Feedback

Processes responsible for the primary forcing, primary response on geospace and the subsequent feedback within geospace and to the atmosphere-space system

Plasma-Neutral Interactions

Processes related to the exchange of energy, mass and momentum between the plasma and the neutral gas of geospace (i.e. plasma drag, plasma chemistry, charge distributions, electrodynamics, plasma instabilities, neutral acceleration, neutral energization)

Cross-Scale Coupling

Processes of one spatial/temporal scale couple to other spatial / temporal scales (i.e., gravity wave – tidal wave interactions, wave-mean flow interactions, small scale Joule and particle heating to global thermal distribution, mean flow to instability processes)


Processes that modify the state of the system leading to a different response (QBO cycle, solar cycle, solar rotation, day/night cycle, geomagnetic cycles) or either processes only occur when certain conditions are met (ESF, strat warming…)


  • Identify Leads for each fundamental process topic
Subcommittee members and their themes would serve as focused efforts within subsequent CEDAR meetings
To lead and represent that effort, to meet with other leads to address overlap, to organize activities for next year\’s meeting, and to begin the process of generating CEDAR report
  • Common items to address by leads
Establish focus groups and schedule
Determine how the specific processes fit within the themes and main question
How might this new dimension broaden the scientific method
How would this effort be put forward to other science communities and public
All leads will meet regularly (telecon) to make overall progress
Work with the CSSC chair and committee on next year\’s meeting and in the production of a CEDAR report

Must not digress

Note the approach does not digress to a particular instrument, location or altitude – must keep eye on themes and fundamental processes which will dictate resources such as instrumentation development and their distribution
