From Gary Bust (gbust at astraspace.net).
This joint CEDAR-GEM workshop intends to allow researchers from the magnetosphere, ionosphere and thermosphere disciplines to come together and discuss current ongoing research with GPS, future possible research topics and collaborations among all the researchers and to discuss new possible techniques and analysis methods that might be use by GPS to further our understanding of the Earth's space physics environment.
The goal of this workshop is to have the scheduled talks be no more than 5 minutes each, and to generate discussions and questions both during the talks and after, for as long as desired. Audience members are encouraged to add a slide or two to the discussion process.
The workshop is separated into 2 sessions. The first session from 16:00-18:00 on Monday has a focus on "GPS-based studies of the Ionosphere and IT System". The second session from 10:00-12:00 on Tuesday has a focus on "GPS TEC, A new tool for investigation the MI system".

- Coster: GPS data in Madrigal
- Galvin: The 2011 Tohoku Tsunami observed in the Ionosphere using GPS TEC
- Valladares: Studies of the low-latitude ionosphere using networks of GPS receivers
- Psiaki: GPS Investigations of Equatorial Ionospheric Scintillation: Receiver Development, Data Collection Campaigns, Inverse Diffraction, & Nonlinear Tomography
- Bust: Closely clustered GPS scintillation arrays in Antarctica
- Morton: Multi-Band GNSS Scintillation at HAARP
- Deshpande: Studying polar ionospheric irregularities using forward modeling and observations from Antarctica
10:00-12:00 Tuesday: GPS TEC, An New Tool for Investigating the MI System
- Murr: An overview of ULF wave observations with GPS TEC

- (c)CEDAR workshop “Ionospheric Data Assimilation: Current Status and Future Plans”, 10:00 – 12:00 on Friday, 1 July 2011, Conveners Bust, Pi, Datta-Barua (http://cedarweb.hao.ucar.edu/wiki/index.php/2011_Workshop:Ionospheric_Data_Assimilation)
From Seebany Datta-Barua <email@example.com>.
“Ionospheric Data Assimilation: Current Status and Future Plans” will review current state-of-the-art techniques in Ionosphere-Thermosphere data assimilation, and serve as a planning platform for a coordinated assessment forum. The development of IT data assimilation requires self-assessment of accuracy, robustness, strengths, and weaknesses of the various assimilation algorithms. This workshop intends to discuss and develop an assessment plan that will continue to foster greater cooperation and interaction among the various research groups into IT Data assimilation begun at previous CEDAR meetings.
For this workshop we welcome all members of the data assimilation community to make brief presentations on the current status of their algorithms and future plans. We also welcome the entire CEDAR / GEM community to be part of the planning discussion, since these data assimilation algorithms are of benefit to the entire community.
Workshop Part 1 (1 hour)
The first half of the workshop will be devoted to brief “state-of-the-field” reports on the current status of IT data assimilation algorithms, and next-stage research and development plans for these algorithms. Confirmed speakers to date include:
- X. Pi
- G. Bust
- S. Datta-Barua
- L. Scherliess
- A. Richmond
Workshop Part 2 (1 hour)
The second half of the workshop (1 hour) will be a planning discussion on developing a community-wide data assimilation self-assessment and validation of various algorithms and the state of IT data assimilation, in a cooperative, joint, and interactive manner.
Topics for the open forum Discussion Session include:
1) Data assimilation test bed
- Simulated data sets and truth
- Actual test data sets and validation data sets
- Metrics to quantify performance improvements
2) Data Assimilation (DA) Workshop
- Define degree of cooperation and sharing ideas / results / problems that is achievable and useful for the whole DA field
- Develop 5 year plan for ionospheric DA field direction to take, cooperatively and individually
- Science topics that DA methods could address over the next 5 years
3) Potential Technical and/or Programmatic Issues
- Implementation issues regarding development of data assimilation test bed
- Workshop issues: When, where, how supported
- How can the data assimilation consortium move forward as a group?
- What are the 2-3 leading technical issues ahead?
