To address system-level CEDAR science questions, we need an effective approach to combining observations obtained from various ground-based sensors (ISR, SuperDARN, magnetometers, imagers, FPIs, and more) as well as space-based sensors (drift meters, magnetometers, particle analyzers, imagers, and more). The objective of this workshop is to identify the challenges of data assimilation and inverse problems for high-latitude electrodynamics and to discuss potential solutions. </div><div style="margin-top: 0px;

Recent observational and modeling studies have revealed clear reaches of terrestrial weather far beyond the Mesosphere Lower Thermosphere (MLT) region into the topside ionosphere. At the same time, the region lends itself to forcing originating from the Sun and solar-wind magnetosphere interactions. The predictability of the SAIR is a fundamental question in Heliophysics, and calls for a paradigm shift from a deterministic to a probabilistic modeling framework. To meet with this contemporary modeling and simulation challenge, we will systematically compare and combine ensemble simulations of a comprehensive whole atmosphere model, coupled with an ionosphere and plasmasphere model called the Integrated Dynamics in Earth’s Atmosphere (IDEA) with global Earth and geospace observations. Building on the National Weather Service's operational ensemble forecasting and data assimilation systems as well as our earlier efforts, we will construct an ensemble forecasting and data assimilation system that will ultimately be capable of assimilating observations from the ground to the SAIR.</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; min-height: 14px; "><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; ">For more information, contact Tomoko Matsuo tomoko.matsuo at <a href="http://colorado.edu/"><span style="text-decoration: underline; color: rgb(25, 86, 238); ">colorado.edu</span></a><span style="text-decoration: underline; color: rgb(25, 86, 238); ">)</span></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font: normal normal normal 12px/normal Helvetica; ">Further information is available at: <a href="http://cires.colorado.edu/jobs/"><span style="text-decoration: underline; color: rgb(25, 86, 238); ">http://cires.colorado.edu/jobs/</span></a></div></div></body></html>
