Dear Colleagues,

We encourage you to submit an abstract to Session NG18  of the 2010 AGU Fall Meeting Session, entitled "Non-Gaussian and non-linear Aspects of Data Assimilation and Predictability in the Geosciences".  A description of the session is included below.

Session Description: Data assimilation (DA) and predictability are important areas of active research in the geosciences. Typically, the underlying dynamical models with these systems are non-linear and as such pose problems for both DA methods, that rely on Gaussian assumptions, and for predictability or sensitivity studies that depend on linear relationships. The purpose of this session is to share ideas that address these aspects of DA and predictability. The areas of interest are: variational DA, ensemble and extended Kalman filters, ensemble based and adjoint sensitivity, Monte Carlo methods, particle filters, Hamiltonian dynamics transforms and other techniques involved with nonlinearity in DA or predictability.

We have three confirmed invited speakers:

Dr. Craig Bishop, Naval Research Laboratory (NRL), Monterey, CA.

Dr. Derek Posselt, Department of Atmospheric, Oceanic, and Space Sciences, University of Michigan, MI.

Prof. Andrew Moore, Ocean Science Department, University of California, CA.

The extended version of the abstract is attached with more detailed areas of interest for this session.  Please feel free to forward the email to colleagues that may be interested in this subject.

The 2010 AGU Fall Meeting is December 13-17, 2010 at the Moscone Convention Center in San Francisco, California, USA.


The deadline to submit an abstract for this session is September 2, 2010, at 23:59 Eastern Daylight Time.  AGU will not accept late submissions.  To submit an abstract, you must be an AGU member or sponsored by an AGU member.


If you have any questions, please feel free to contact us.


Dr. Steven Fletcher, CIRA, Colorado State University, Fort Collins, CO.

Prof. Brian Ancell, Atmospheric Science Group, Texas Tech University, Lubbock, TX
