The development of numerical models of the thermosphere and ionosphere has reached an apex point where we need to ask what are the challenges ahead and the opportunities we can exploit; at the same time, observations are scarce in the thermosphere but plentiful in the ionosphere and there is an opportunity to use the latter to aid theory in both the thermosphere and ionosphere. Informed by outstanding science questions of the TIS, only a holistic system approach can guide the integration of theory with observations. Such a system-wide approach supports the CEDAR “New dimension and Strategic Vision” for 2013, and specifically the CEDAR Strategic Thrust #1 (“Encourage and undertake a systems perspective to geospace”). In addition, this workshop supports the Heliophysics Decadal Survey goal to “Determine the dynamics and coupling of Earth’s magnetosphere, ionosphere, and atmosphere and their response to solar and terrestrial inputs.” Finally, the workshop responds to Imperative #3 of the Decadal Survey (“Integrate data from a diverse set of observations across a range of scales, coordinated with theory and modeling efforts, to develop a comprehensive understanding of plasma-neutral coupling processes and the theoretical underpinning for space weather prediction.”)


As the past several years have seen the development of integrated systems of thermospheric and ionospheric physics, times are now mature for reflecting on how observations are used along with theory not just as validation tools, but also as integral components of a predictive capability of the thermosphere-ionosphere system (TIS). While some work has already commenced in integrating observations with models for improving forecasting skills, the CEDAR community is still identifying the technological aspects that can be used to augment predictions and advance theoretical understanding of the TIS, as opposed to the lower atmosphere where technologies, observations, and methodologies have undergone many years of development. Given the natural choice for aeronomers to be primarily observationalist or theorist, there still exists a continuing need for the CEDAR community to exploit the vast knowledge base that enables bringing both these sub-communities together. In fact, the design and success of current and future TIS forecasting systems depend on such fusion of knowledge and opportunities. Ultimately, future advances in the fundamental science of accurate prediction of the TIS over time scales ranging from hours to days to years will require a shift in the community away from treating theory and observations as separate compartmentalized topics and toward an integrated treatment of both theory and observations. The goals of this workshop are to (1) discuss how these two aspects of the TIS are now treated and can be integrated by the CEDAR community; (2) examine how observations of both neutrals and electrodynamic properties can help advance theory; (3) identify the key observational capabilities required for data-model integration to generate reliable forecasting and guide the future development of instrumentation infrastructure; (4) determine what lessons could be learned from numerical weather prediction systems developed for the lower atmosphere; (5) identify key science questions informed by these discussions that can guide future research into developing an integrated system approach for TIS prediction . We plan to organize the workshop around two sessions. In the first session, we solicit speakers who provide an update on the current status of observations and the technologies used to integrate observations with theory, with a special focus on challenges that the community faces; we are seeking contributions from both the upper and lower atmosphere. In the second session, we solicit speakers from the theory of aeronomy who highlight challenges of the coupled TIS and how observations can become useful to advance theory.
