Book: Probabilistic Forecasting and Bayesian Data Assimilation

sebastian_book.jpg 16.6.2015. New Book: Probabilistic Forecasting and Bayesian Data Assimilation

AUTHORS: Sebastian Reich, Universität Potsdam, Germany and University of ReadingColin Cotter, Imperial College London

In this book the authors describe the principles and methods behind probabilistic forecasting and Bayesian data assimilation. Instead of focusing on particular application areas, the authors adopt a general dynamical systems approach, with a profusion of low-dimensional, discrete-time numerical examples designed to build intuition about the subject. Part I explains the mathematical framework of ensemble-based probabilistic forecasting and uncertainty quantification. Part II is devoted to Bayesian filtering algorithms, from classical data assimilation algorithms such as the Kalman filter, variational techniques, and sequential Monte Carlo methods, through to more recent developments such as the ensemble Kalman filter and ensemble transform filters. The McKean approach to sequential filtering in combination with coupling of measures serves as a unifying mathematical framework throughout Part II. Assuming only some basic familiarity with probability, this book is an ideal introduction for graduate students in applied mathematics, computer science, engineering, geoscience and other emerging application areas.

Free Webinar: Verification, Validation, and Predictive Capability: What’s What?

May 15, 2015. Dear Colleague, please have a look at the following seminar.

Thursday May 28th 2015 
11:00 EDT, 08:00 PDT, 16:00 BST, 17:00 CEST

Engineering organizations must increasingly rely on computational simulation for design and predicted performance, reliability, and safety of systems. Computational analysts, designers, decision makers, and project managers who rely on simulation should ensure that practical techniques and methods are in-place for assessing simulation credibility.

This webinar presents an introduction to the topics of verification, validation, and predictive capability. These topics are applicable to essentially all engineering and science applications, including fluid dynamics, heat transfer, solid mechanics, and structural dynamics. The mathematical models for the systems of interest are typically given by partial differential or integral equations representing initial value and boundary value problems. The computer codes that implement the mathematical models can be developed by commercial, corporate, government, or research organizations; but they should all be subjected to rigorous testing by way of verification procedures. The accuracy of the mathematical models coded into software are assessed by way of comparisons of results with experimental measurements; referred to as validation activities.

This webinar will sketch a framework for incorporating a wide range of error and uncertainty sources identified during the mathematical modeling, verification, and validation processes, with the goal of estimating the total predictive uncertainty of the simulation. This is referred to as predictive capability because typically no experimental measurements are available for the systems or subsystems at the application conditions of interest.

IMA Numerical Methods for Simulation, UK, Sep 2015

Feb 27, 2015. Developments in numerical methods underpin simulations in many ways, for example in any area where high dimensional problems are governed by differential equations. Computational fluid dynamics has driven many developments in this area; however there is a wide range of application areas where the problems, and indeed solution techniques may be similar. Numerical methods are important in diverse areas such as geophysical modelling, fluid-structure interaction, high-dimensional dynamical systems, weather prediction, climate modelling, oil reservoir simulation, and so on. The conference will bring together application specialists, applied mathematicians, numerical analysts and computational scientists who develop and use numerical simulations. Applications which focus on data assimilation, inverse problems, uncertainties or control, which contain as a major component a high-dimensional forward model, will also be represented.

Conference themes: Higher-order discretization methods; Methods for uncertainty quantification; Multi-physics / multi-material / multi-scale simulation; High performance computing (including energy efficient algorithms and algorithms for emerging architectures); Optimization / control / design / inverse problems; Numerical analysis / numerical linear algebra and preconditioning

Abstracts are requested for contributed talks in any area consistent with the conference themes. Talks will be accepted for either oral or poster presentation on the basis of a one- page extended abstract in PDF format, which should be sent via email to conferences@ima.org.uk by Friday 27 March 2015.

For further information, please see the conference webpage: http://ima.org.uk/conferences/conferences_calendar/numerical_methods_for_simulation.html

Reminder and additional info: Workshop on Meteorological Sensitivity Analysis and Data Assimilation

Workshop on Meteorological Sensitivity Analysis and Data Assimilation 1-5 June 2015 Roanoke, West Virginia

5.2.2015. Abstracts are due tomorrow. Please follow the instructions in the 3rd announcement, a copy of which is appended to this e-mail. We realize that some may be late, but please get them to us ASAP so that we can begin to plan the program. A list of all received abstracts will be broadcast to everyone on our mailing list of interested persons next week. Later we will send instructions for registering at the hotel.

Some people have questions regarding the conference cost and limits on costs for lodging and meals imposed by their funding agencies. The U.S. Government, for example, considers rural West Virginia as an inexpensive location, but its limits will only get you a tent to sleep in and a Mac Donald's to eat in (which are only slight exaggerations). Both our room and meal costs exceed those limits, although the way the conference is priced, I do not know what those amounts actually are: we are getting a “conference rate” that includes the costs of conference room and audio-visual rentals, coffee breaks, various hotel fees, besides individual room and meals. This is necessary because we have no way to collect large conference registration fees from everyone that would otherwise pay for these necessary things. The hotel is therefore collecting these by rolling them into individual's costs.

I have discussed this problem at length with the hotel, who of course have their own accounting rules to follow. Nonetheless, they have been accommodating. So what may help some of you is that, upon paying your hotel bill, you will receive 2 papers. One will be be a copy of the “handbill.pdf” breaking down the conference rate into 3 components. The rate for “students” is actually the rate for anyone sharing a room. The 2nd page of the “hotelfolio.pdf” is essentially the normal bill, except yours will have the “Resort fee” rolled into your “conference package.” Note that this fee contains, among other things, your daily entrance fee to the State Park in which the hotel is located. Also note that travel managers who want to make your attendance difficult may thereby get confused by the applied government taxes, but this is the best we can do. So, if you expect a problem, get it cleared before you register. Some managers, however, are more lenient about regulations for costs that otherwise appear reasonable.

For postdocs and students who have requested funds but who have not yet received a definitive commitment from us, we are still working on obtaining additional funds. We hope to know more by early March.

A copy of the 3rd Announcement follows:

This announcement is being sent to the 90+ researchers who have expressed an interest in attending the workshop. We are requesting titles and short (<300 word) abstracts of what you would like to present at the workshop. These should be provided to us by 6 Feb. 2015 in the format described below. Presenters will be allowed to reasonably modify their abstract prior to our publishing the final program and list of abstracts on our website before the workshop's start. Please follow the guidelines below.

1. Submit only one abstract. Your name may be included on other abstracts only if your coauthors truly intend to present those others themselves.

2. An abstract should be sufficient for the committee to confirm its relevance to the workshop and to assign its most appropriate place in the program. Use the format described at the end of this mailing.

3. Do not attempt to simply describe all the wonderful work you have performed during the past few years, but instead focus on just a few things that you have learned that may be of interest to most of us. Since the audience will want to evaluate your contribution rather than just see or hear it, better is to be thorough and specific rather than vague and general.

4. Indicate whether you prefer an oral or poster presentation or either. Note that the program will allow ample dedicated time for posters but that there may not be time for all who request an oral time slot. The latter will be approximately 20 minutes each, plus additional time for questions/discussion. You should not need to include descriptions of general fundamentals since these should be described in the pre-workshop tutorials or in the more detailed presentations of issues in earlier invited, review-like talks.

5. Hotel reservations will be required by sometime in April, so you will be notified of acceptance of your abstract before 6 March, at which time we also hope to provide a rough program draft.

6. The cost for 5 days/nights room, meals, registration, taxes (combined expenses payable to the hotel) will be approximately $1300 (single occupancy) or $885 (double occupancy). Information about transport options between the hotel and Pittsburgh International Airport (PIT) will be forthcoming.

7. Students and postdocs who have requested partial support from workshop funds will receive further instructions within the next few days.

8. For information previously provided see the workshop website: http://gmao.gsfc.nasa.gov/events/adjoint_workshop-10/

Training Course on Data Assimilation at CERFACS

22.1.2015. Data assimilation has become an important component of modelling for a growing number of applications in the geosciences and in engineering. This training course will provide an overview of the theory and practical methods of data assimilation. First the basic concepts from statistical estimation theory and nonlinear optimization will be given. The classical variational and Kalman filtering approaches to data assimilation will then be described. The lectures will also cover more specialized topics including covariance modelling and estimation, advanced minimization algorithms, preconditioning, and hybrid ensemble-variational methods. The lectures on the theory will be complemented by both practical exercises and presentations on specific applications at CERFACS in the geosciences (oceanography, atmospheric chemistry and hydrology/hydraulics).
