Data assimilation for extreme ionospheric events: observing system experiments of the September 26, 2011 geomagnetic storm
14 Apr 2016  Presentations
As increasingly sophisticated ground and spacebased technological systems that depend on the nearEarth space environment are being built, vulnerabilities to variations in the ionosphere are also increasing. These vulnerabilities are especially prominent during extreme spaceweather events,...

Hybrid EnKF and Particle Filter: Lagrangian DA and Parameter Estimation
06 Nov 2015  Presentations
Dealing with high dimensional systems is one of the central problems of data assimilation. A strategy is proposed here for systems that enjoys a skewproduct structure. Christopher Jones, University of North Carolina at Chapel Hill, presents joint work with Naratip...

12 May 2015  Presentations
Charles Jackson, University of Texas, AustinDualstate Behavior of the Community Climate System ModelIce age climate between 80,000 and 11,000 years ago experienced abrupt (< 10 year) globalscale climate transitions every few thousand years. Evidence and theory suggests such behavior may be...

Midwest Mathematics and Climate Conference  Day 2 Morning Session
12 May 2015  Presentations
Juan Restrepo, Oregon State UniversityData AssimilationAccounting for uncertainties has led us to alter our expectations of what is predictable and how such predictions compare to nature. A significant effort, in recent years, has been placed on creating new uncertainty quantification techniques,...
