<b>Overview</b>

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".

*(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 <seebany.datta-barua at sjsu.edu>.

<b>Overview</b>

“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.

<b>Workshop Part 1 (1 hour)</b>

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

<b>Workshop Part 2 (1 hour)</b>

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?
