CEDAR email: CEDAR Grand Challenge Workshop: Coordinated Ground and Space-based Observations of the Ionosphere-Thermosphere System

[Katelynn Greer]

Dear CEDAR community,

We would like to invite you to participate in the 2019 CEDAR Grand Challenge Workshop: Coordinated Ground and Space-based Observations of the Ionosphere-Thermosphere System. There will be two sessions scheduled for Monday 17 June 13:30-15:30 and Tuesday June 18th 10:00-12:00.

With the recent launch of the GOLD mission of opportunity (25 January 2018), and the upcoming launches of the ICON and COSMIC-2 spacecraft, both expected to launch during 2019, our community has a unique, perhaps unprecedented opportunity to investigate the thermosphere-ionosphere system.  These three missions  (GOLD, ICON, and COSMIC-2 ) will provide unique opportunities for probing both the upper neutral atmosphere (optic observations by GOLD and ICON optical instruments) and ionosphere  (electron density profiles from the bottom ionosphere border to 500 km altitude by COSMIC-2 radio occultation (RO) as well as in-situ plasma measurements onboard  ICON and COSMIC-2  on equatorial an polar planes). With the combination of these observations with the ground-based facilities data (such as ISR's, ionosondes, GNSS networks, FPIs, lidars, and all-sky cameras), new opportunities for the investigation of coupling processes within the ITM system will be presented. In particular, the combination of COSMIC-2 RO, GOLD, Jicamarca ISR and Julia coherent radars, and ground-based GNSS observations will be a key for understanding of the EIA variability and the formation and evolution of the plasma bubbles.  Coordinated ground- and space-based observations will bring more detailed specification of the physical processes in the ITM system, improvement of models, and also improve our understanding of the impact of these processes on performance of critical technological systems that use transionospheric radio links including GNSS.  How current theories fit these observations will also be explored.

This workshop provides a forum for the community of investigators studying the thermosphere-ionosphere system of night time phenomena, dayglow variability and the thermospheric thermal structure using coordinated observations from ground- and space-based instruments, including GOLD, ICON and COSMIC-2. Contributions are welcome in the form of brief focused presentations. Of particular interest are investigations combining ground-based and space-based observations, opportunities for campaigns, and/or proposals for coordinated ground- and space-based instruments. The sessions will include time for open discussion assessing progress and discussing future directions.

If you would like to be involved in this Grand Challenge, please get in touch with us.  We are soliciting both speakers and opportunities for campaigns.  We look forward to seeing you in Santa Fe!
