March 10, 2017. Dear Colleagues: 3rd and final Notice:

Abstracts are due on Sunday, March 12 for the following joint session at IAPSO/IAMAS/IAGA Joint Assembly (August 27 - September 1, 2017, Cape Town, South Africa):


Session Description: The fields of Earth system data assimilation and ensemble forecasting are confronted with both new and long standing challenges in probabilistic state estimation: (i) the identification and representation of systematic and stochastic aspects of model error; (ii) coupled systems; (iii) non-Gaussian uncertainty distributions; (iv) ensemble forecast verification and post processing; (v) the use of multi-model and/or multi-resolution ensembles; (vi) achieving balanced initial states that are free of artificial transient waves (or oscillations) ; (vii) the use of analogue observation system simulation experiments with both numerical models and/or laboratory systems to validate and improve real state estimation schemes, and (viii) strategies for dealing with non-linear observation operators in Ensemble Kalman filters. This symposium will bring together atmospheric, oceanic, and solid Earth data assimilation and ensemble forecasting experts to jointly address the aforementioned challenges and create an exchange of ideas likely to advance Earth system state estimation across its many facets. Papers are invited on all aspects of data assimilation and ensemble forecasting for the ocean, atmosphere and solid Earth. Presentations pertaining to coupled model forecasting and coupled model data assimilation are particularly encouraged.

Invited presentations cover advances and challenges listed above, and overviews of data assimilation in Earth science research and applications. Confirmed speakers are as follows:

Dr. C. Snyder (NCAR, USA) Dr. Neill Bowler (Met Office, UK) Dr. M. Martin (Met. Office, UK) Prof. M. Mu (Chinese Academy of Sciences) Prof. N. Gillet (UJF, France) Dr. A. Donnellan (JPL, USA) Dr. C. Finlay (DTU, Denmark) Prof. C. Edwards (UCSC, USA)

We also welcome papers aimed at increasing understanding of the fundamental limits of predictability. Such papers could include: analyses of the relevant initial error dynamics and model error physics, ideas for estimating error growth that limits predictability, methods that attempt to quantify the predictability of specific phenomena in the solid Earth, ocean or atmosphere. Contributions from young researchers and early career scientists are in particular welcome. We look forward to meeting you in Cape Town.

IMA Conference on Inverse Problems from Theory to Application

Tuesday 19 - Thursday 21 September 2017 Isaac Newton Institute, Cambridge, UK


An inverse problem denotes the task of computing an unknown physical quantity from indirect measurements. The corresponding forward problem maps the physical quantity to the measurements. In most realistic situations the solution of the inverse problem is challenging, complicated by incomplete and noisy measurements, as well as non-invertible forward operators which render the inverse problem ill-posed (that is lack of stability and/or uniqueness of solutions). Inverse problems appear in many practical applications in biology, medicine, weather forecasting, chemistry, engineering, physics, to name but a few, and their analysis and solution presents considerable challenges in mathematics and statistics. This conference will bring together mathematicians and statisticians, working on theoretical and numerical aspects of inverse problems, and engineers, physicists and other scientists, working on challenging inverse problem applications. We welcome industrial representatives, doctoral students, early career and established academics working in this field to attend.

Conference topics:

  • Imaging
  • Regularisation theory
  • Statistical inverse problems
  • Sampling
  • Data assimilation
  • Inverse problem applications

Call for Papers:

Papers will be accepted for the conference based on a 300 word abstract for oral or poster presentation. Abstracts should be submitted by 30 April via

'Invisibility cloaks' for buildings could protect them from earthquakes

Nov 27, 2016. Researchers are developing large structures inspired by 'cloaking' materials for sound and light, which can offer protection against seismic waves.

Earthquakes travel in waves, much as sound and light do. Scientists have previously designed materials with internal structures that interfere with the propagation of sound and light, and now researchers are working on making bigger versions of these structures, which could be used to control the propagation of earthquakes.

Workshop on Wind Profiles and Mesoscale Data Assimilation

Dear Colleage, please note the upcoming

Workshop on Wind Profiles and Mesoscale Data Assimilation
Ljubljana, 19-20 September 2016. 

About fifty years ago the first sensitivity experiments on the importance of various observations for Numerical Weather Prediction (NWP) showed that “Not all data are equal in their information-yielding capacity. Some are more equal than others. This tells us that if there is a choice as to what can be measured, then one variable may be preferable over another.” (Smagorinsky, 1969). Wind information, the “more equal” one, remains the main missing component of the global observing system. Observations of the vertical wind profiles by the ESA ADM-Aeolus mission have been demonstrated to have the potential of providing a significant improvement in NWP, primarily in the tropics where the lack of wind information is most critical for the global NWP. The same dynamical and data issues that apply to the tropics are shared by mesoscale NWP models.

The workshop aims to discuss some open issues in mesoscale data assimilation for NWP. In particular, the workshop is an opportunity to present latest advances and discuss new ideas related to the following topics:

  Application of ADM-Aeolus winds in mesoscale models  
  Wind observations and balanced initial conditions on mesoscale
  Gravity waves versus imbalance in data assimilation  

Presentations on the operational applications and research related to the assimilation of wind observations and the balance issues in mesoscale data assimilation are welcome.

Registration and contact: Matic Savli, and Nedjeljka Zagar,

Workshop is sponsored by the University of Ljubljana, Faculty of mathematics and physics, project “Mesoscale wind profile and data assimilation for NWP” funded by the European Space Agency, Plan for European Cooperating States.

The 8th International Conference on Inverse Problems and Related Topics will take place at Ewha womans University in Seoul from June 27 (Monday) to July 1 (Friday), 2016. This series of conferences were previously held in Hong Kong (2002), Shanghai (2004), Hokkaido (2006), Daejeon (2009), Hong Kong (2010), Nanjing (2012), and Taipei (2014). This conference features speakers from both theoretical (mathematics) and applied (engineering) aspects of inverse problems. It aims to strengthen the interaction and, most importantly, to nurture collaborations between two groups of scientists. In addition, one of the focuses of the conference is to promote young scholars in inverse problems in the Asia-Pacific region.

Inverse problems arise in many areas of science including mathematics, engineering, medicine, physics, and geophysics. The varieties of their applications are enormous such as medical imaging, oil exploration, radar, sonar and seismology. In the last twenty years the active research carried out in the field of inverse problems has made it become a very promising interdisciplinary topic.

MCRN Colloquium Webinar

Monday, April 11, 2016, 4pm EDT*: Juan Durazo (Arizona State University). Data assimilation for extreme ionospheric events: observing system experiments of the September 26, 2011 geomagnetic storm

Abstract: As increasingly sophisticated ground- and space-based technological systems that depend on the near-Earth space environment are being built, vulnerabilities to variations in the ionosphere are also increasing. These vulnerabilities are especially prominent during extreme space-weather events, where satellite communication systems or terrestrial power grid are at risk of being disrupted. Data assimilation has become an essential tool for the specification of ionospheric space-weather, in particular the evolution of its electron density distribution. In this study, we use the Local Ensemble Transform Kalman Filter (LETKF) data assimilation scheme and the Thermosphere-Ionosphere-Electrodynamics Global Circulation Model (TIEGCM) to track and forecast the global electron density distribution during a recent geomagnetic storm in September 26, 2011. Synthetic observations are generated and are assimilated into the ensemble forecast at every hour, using observations available within 30 minutes of analysis time. As a system that is strongly driven by external influences, the quality ionospheric forecasts depends on the estimation of these drivers, which include solar conditions, geomagnetic activity, and the state of the charge-neutral thermosphere, which is intimately coupled with the ionosphere. Thus the data assimilation system employed is extended to estimate these drivers in addition to the electron density state. Results show that the LETKF can adequately handle the inverse problem of using the available observations to estimate the ionospheric drivers that generated them, in addition to estimating the global distribution of electron density during this extreme space-weather event.

* This talk begins at 20:00 GMT = 10:00 HAST = 13:00 PDT = 13:00 MST = 14:00 MDT = 15:00 CDT = 16:00 EDT= 21:00 BST = 22:00 CEST, and Tuesday, the 12th, at 1:30 IST = 5:00 JST = 5:30 ACST = 6:00 AEST = 8:00 NZST

Inverse Modeling Book now available

Dear Colleague, our book on Inverse Modeling: An introduction to the theory and methods of inverse problems and data assimilation (IOP Expanding Physics) by Gen Nakamura (Author), Roland Potthast (Author) is now available on Amazon at Inverse Modeling Amazon.

Cover Text by the Publisher:

“This book provides a comprehensive introduction to the techniques, tools and methods for inverse problems and data assimilation. Inverse problems are widespread today in science and technology, and this book is written at the interface between mathematics and applications, designed for students, researchers and developers in mathematics, physics, engineering, acoustics, electromagnetics, meteorology, biology, environmental and other applied sciences.

Basic analytic questions and tools are introduced, as well as a wide variety of concepts, methods and approaches to formulate and solve inverse problems, among others classical regularization and iterative methods, but also more recent approaches like sampling and probe methods, field reconstruction techniques in acoustics and electromagnetics and source reconstruction. In the framework of data assimilation, stochastic and deterministic methods are becoming more and more intertwined both variational and ensemble data assimilation methods are introduced, as well as stochastic and deterministic viewpoints and analysis. Applications range from neural kernel reconstruction to inverse acoustic and electromagnetic scattering and thermography, from magnetic tomography for fuel cells or in a medical environment to weather forecasting and earth science. OCTAVE /MATLAB codes are included, which serve as a first step towards simulations and more sophisticated inversion or data assimilation algorithms.”

Workshop Basic Data Assimilation Concepts

Feb 6, 2016. Dear Colleague, please note the Workshop on Basic Data Assimilation Concepts which takes place on 11 September 2016, Trieste, Italy, organized by the European Meteorological Society.

Lecturers: Prof. Dr. Roland Potthast, DWD (Research and Development, Head Division Data Assimilation), Dr. Martin Weissmann, LMU Hans–Ertel–Centre for Weather Research, Head of Data Assimilation Branch


The workshop will provide an introduction to data assimilation concepts, methods and techniques for forecasters and meteorologists.

To calculate weather forecasts on short or longer temporal scales, measurement data need to be fused into a coherent estimate of the current state of the atmosphere. These techniques are also of growing importance for nowcasting, and they are an important ingredient for climate monitoring and to calibrate climate projections. When measurements are integrated into model states, we usually speak of data assimilation.

The workshop provides a basic introduction to the ideas, set-up, properties, techniques and results which are behind data assimilation and data fusion. Its goal is to enable forecasters and users to understand the role of measurements, the capabilities and limitations of assimilation, and to gain insight into the whole NWP system which consists of a data assimilation cycle and forecast runs. A particular focus will be placed on the determination of uncertainty and risk within the analysis and forecast, which is a key goal of modern ensemble data assimilation systems.

Mathematics in Imaging Congress of the Optical Society OSA in Heidelberg 2016

Jan 13, 2016. Dear Colleague, please note the Congress “Mathematics in Imaging” which is taking place

  25 - 28 July 2016
  Kongresshaus Stadthalle Heidelberg, Heidelberg, Germany 

Mathematical Imaging covers mathematical and computational methods for modeling the physics of imaging methods and for providing stable and resolved solutions to the inverse problem of image reconstruction. It captures leading edge fundamental developments in imaging science and has applications in photonics, biomedical imaging, astronomy, and remote sensing. Imaging methods are constrained by the experimental data which are corrupted by measurement and medium noises and depend nonlinearly on the imaged object material and geometric parameters. Many of the fundamental problems in image reconstruction methods are shared across different disciplines, including optics, acoustics, seismic imaging, and synthetic aperture radar. These include optimal representations, resolution and stability estimates, optimal design approaches, and model reduction techniques.

Mathematical Imaging provides a platform for a cross fertilization between mathematical, computational, physical, and engineering disciplines related to imaging and inverse problems. Because of the breadth involved, papers highlighting either the interdisciplinary flavor of imaging methodologies or the fundamental mathematical and computational issues in imaging are particularly encouraged. Topic Categories

  Inverse scattering, regularization, constraints,  inversion in the multiple scattering regime
  Shape optimization
  Blind deconvolution
  Coherent imaging systems (holographic imaging, synthetic aperture radar ...)
  Phaseless imaging (X-ray imaging ...)
  3D imaging (tomographies, microscopy ...)
  Imaging through turbulent, random or highly scattering media
  Biomedical imaging and hybrid imaging
  Biomimetic imaging
  Inverse problems related to design of metamaterials, metasurfaces, and cloaking

Description of the session

Inverse Problems are encountered in many fields of Geosciences, for the purpose of either prediction or inference. One class of inverse problems, in the context of predictability, is assimilation of observations in dynamical models of the system under study.

This session will be devoted to the presentation and discussion of methods for inverse problems and data assimilation, in ocean and atmosphere dynamics, solid earth geophysics, atmospheric chemistry, hydrology and, more generally, in all fields of geophysics.

Data assimilation in coupled models (for example ocean/atmosphere models) is an emerging area of development for forecasting and reanalysis at operational centres. We particularly encourage contributions related to research aimed at understanding and developing such coupled data assimilation systems.

We also encourage reports on advanced methods, and related mathematical developments, suitable for situations in which local linear and Gaussian hypotheses are not valid and/or in the presence of model error. Contributions dealing with algorithmic aspects and numerical implementation of the solution of inverse problems are welcome, as well as contributions dealing with quantification of uncertainty in inverse and data assimilation problems.

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.
