This workshop will address several points described in the Strategic Thrust #4 “to develop Observational and Instrumentation Strategies for Geospace System Studies” and # 6 “to manage, Mine and Manipulate Geoscience Data and Methods.” Specifically, we will discuss coordinated multi-instrumented campaigns and perform statistical analysis that uses more than one type of instrument. We will also present results of data mining that include extensive resources provided by distributed observatories and incoherent scatter radars and conduct: • Continued evolution of data assimilation schemes to integrate data with physics-based models for improved predictive capability. • Develop advanced analysis techniques needed for efficient fusion of observations into sophisticated inference models. • Discussion of data distribution and network management required for long-term science and space weather support. This workshop is also directed to the study of the ionosphere-thermosphere system in an integrated fashion and improvement in the space weather and climatology capabilities emphasized in the 2013-2022 Decadal Survey.


This session will present plans, initial results, and or scientific goals to be carried out by the different groups that are presently building DASI networks. We hope to have most of the teams that are currently deploying, expanding or upgrading instrument arrays in the American sector or other regions of the Globe to be represented in this session. We will use this opportunity to provide a forum to discuss deployment strategies and receive suggestions from the CEDAR community. During the last ten years, it has become evident the necessity to probe extended areas and volumes of the IT system. Accordingly, the CEDAR and the US Space Science community have fielded coherent scatter radars, ionosonde networks, Fabry-Perot interferometers, all-sky imagers, GPS receivers, and multiple RF receivers. Some of these networks are collocated with incoherent scatter radars being able to measure the four basic ionospheric physical parameters and thus increasing the observing capabilities of single-site observatories.
