GPS/GNSS Tomography for Atmospheric Sciences Special Session at EGU

Dec 16, 2013. Dear Colleague, The next General Assembly of the European Geosciences Union will be held in Vienna, Austria, 27 April – 02 May 2014. We draw your attention to session G5.2 titled “Atmospheric Remote Sensing with Space Geodetic Techniques” chaired by us. The corresponding session abstract is included at the end of this mail and it can also be found at We invite you to contribute actively to the session by submitting abstracts. Notice that the DEADLINE FOR ABSTRACT SUBMISSION IS JANUARY 16, 2014. Here is a link about how to submit an abstract: abstract submission. With kind regards and best wishes for you and your family during the seasonal holidays. We are looking forward to welcoming you in Vienna! Rosa Pacione and Henrik Vedel.

Session Abstract.

The ability to do atmospheric sensing of the neutral atmosphere (troposphere 
and stratosphere) by space geodetic techniques has improved considerably over 
the last decade as a result of technological advances, larger regional and 
global ground-based networks, satellite-based   missions and developments of 
appropriate models and algorithms. Water vapour is under sampled in current 
operational meteorological and climate observing systems. Advancements in 
Numerical Weather Prediction (NWP) Models (higher resolution and hourly 
cycling update), to improve forecasting of extreme precipitation, requires 
GNSS observations with better timeliness as well as spatial and temporal 
resolution, than currently available. The existence of more than 15 years of 
homogeneously reprocessed observations from permanent GNSS stations worldwide 
has high potential for monitoring trends and variability in atmospheric water 
vapour which will enable evaluation of systematic biases from a range of 
instrumentation, improve the knowledge of climatic trends of atmospheric 
water vapour and also be of benefit to global and regional NWP reanalyses 
and climate model simulations. NWP data has recently been used for deriving 
improved mapping functions. In Real-Time GNSS processing there is currently 
an interest in using atmospheric NWP data to initialise Precise Point 
Positioning (PPP) processing algorithms which can provide shorter convergence 
time and improve positioning. We welcome contributions on the subjects below, 
but notice that also other subjects are welcome: Physical modelling of the 
neutral atmosphere using ground-based and radio-occultation data. Multi-GNSS, 
Real-Time and reprocessed tropospheric products. Studies on how to mitigate 
atmospheric effects for improving GNSS positioning and navigation, as well 
as observations at radio wavelengths. Technique validation, inter-technique 
comparisons and inter-system calibration. Usage of GNSS measurements in 
weather forecasting (e.g., NWP and now-casting) and in climate 
monitoring. Usage of NWP data in PPP processing algorithms.

The 6th EnKF Workshop, 19-22 May 2014

Dec 3, 2013. On behave of the organizing committee, Peter Houtekamer and I are pleased to announce that the 6th EnKF Data Assimilation Workshop will be held at the Beaver Hollow Conference Center ( just outside of Buffalo, New York. The dates of the workshop will be May 18-22, 2014 arriving on the 18th for dinner and departing the afternoon of 22nd. This will be the sixth in a series of relaxed workshops on the EnKF with emphasis on the atmospheric applications from convective to global scales, including hybrid, coupling and comparison to traditional variational methods. We hope that many of you will be able to attend. We are extending this from the past 2.5 days to 3.5 days to allow more talks given the increased participation and growing ranges of subject areas of interests.

Some rationale for the change in workshop location: Given the Albany/Rensselaerville conference facility is maximized last time, and with expected demands for more seats/rooms for the workshop, I have done some extensive search for similar venues but with more space and rooms. For the past couple of weeks, I have been investigating and negotiating with this conference resort in NY state but near Buffalo and Niagara Falls. Some of the information from this resort is attached below. I went for an exploratory trip last weekend and spent in the resort for the night. The resort can hold more than 150 guests and the facility, food, hotel, meeting, and dinning rooms and recreations are very impressive. The price in the forwarded contract is reasonable though tentative. You can check out their website at: It is about half an hour drive from the Buffalo, NY airport or 2 hours from Toronto airport.

At this point, we are looking to get an initial head count since I will need to work with the resort to finalize a contract for how many rooms they can to guarantee for us, and how many we can need. The primary announcement of the workshop goes to the past attendees. You may get multiple copies of email if you are on both lists. For those whose name appeared on the list for the first time, you were added either based on your request or recommendation from one of the veterans in the past. Feel free to suggest other colleagues you think would be interested in the workshop but, since space in the meeting room is limited, please do not forward this message directly to others.

Please reply to my new colleague Prof. Steven Greybush (who is cc'd and will be handling the workshop logistics and abstracts) and me if you, your students or postdocs will be attending. Please be specific on how many people will be attending from your group, their names and email addresses so we can inform them in subsequent announcement. Please do not call the conference center to make reservations just yet.

The agendas and talks from the previous four workshops of 2006, 2008, 2010 and 2012 can be accessed at

Besides Peter and me, our organizing committee includes

Math of the Planet Earth: New Doctoral Training Centre with 76 PhD Studentships 2014-19

Nov 22, 2013. Climate change represents an urgent challenge for humanity. Quantifying uncertainty in long‐term climate prediction and estimating the potential strength of extreme meteorological events in the face of global warming are very difficult research questions, with large economic and societal impacts that will only grow in the future.

In response to this challenge, Imperial College London and the University of Reading have joined forces to create the EPSRC Centre for Doctoral Training (CDT) Mathematics of Planet Earth (MPE). Students in the MPE CDT will receive cohort-based PhD training in the mathematical and computational techniques needed to understand, predict and quantify risk and uncertainty for extreme weather and climate change. In particular, our PhD students will receive training which ranges from the data-driven domain represented by statistics, to the model-driven domain represented by analysis and mechanics.

This is the challenge that the CDT as a whole will address, and each student will be able to choose the particular areas of research that suit their individual taste and talents. The MPE CDT students will graduate with substantial, interdisciplinary experience in applying cutting-edge mathematics to challenging and urgent problems, and will have developed the teamwork, communication, management and leadership skills needed for a successful career.

The MPE CDT brings together Two world class academic centres, Imperial College London and University of Reading linked together via Grantham Institute for Climate Change External partners including world-leading weather and climate services based in the UK (including the Met Office and ECMWF) and leading national and international centres of research and doctoral training in weather and climate science Representatives of key commercial sectors, including energy, water, marine, and insurance, where there is large demand for our graduates.

New Book: Large Scale Inverse Problems in the Earth Sciences

7. Nov. 2013. Large Scale Inverse Problems - Computational Methods and Applications in the Earth Sciences (2013) Edited by M. Cullen, M.A. Freitag, S. Kindermann and R. Scheichl Radon Series on Computational and Applied Mathematics 13

This book is the second in a three volume series recording the Radon Special Semester on “Multiscale Simulation & Analysis in Energy and the Environment” that took place in Linz, Austria, October-December 2011. This volume tries to highlight and address commonalities in the mathematical and computational procedures typically used in large-scale inverse problems and in data assimilation within different forefront applications.

The solution of inverse problems is fundamental to a wide variety of applications such as weather forecasting, medical tomography, and oil exploration. Regularisation techniques are needed to ensure solutions of sufficient quality to be useful, and soundly theoretically based. This book addresses the common techniques required for all the applications, and is thus truly interdisciplinary.

It records the achievements of Workshop 2 “Large Scale Inverse Problems and Applications in the Earth Sciences” that brought together theoretical experts in inverse problems and data assimilation with practitioners working on practical as well as theoretical aspects of large scale inverse problems that arise in the earth sciences.

New Book: Direct and Inverse Problems in Wave Propagation and Applications

7. Nov. 2013. Direct and Inverse Problems in Wave Propagation and Applications Edited by I.G. Graham, U. Langer, J.M. Melenk, M. Sini (2013) Radon Series on Computational and Applied Mathematics 14

This book is the third volume of a three volume series recording the Radon Special Semester on “Multiscale Simulation & Analysis in Energy and the Environment” that took place in Linz, Austria, October-December 2011. This volume surveys recent developments in the analysis of wave propagation problems. The topics covered include aspects of the forward problem and problems in inverse problems, as well as applications in the earth sciences.

Wave propagation problems are ubiquitous in environmental applications such as seismic analysis, acoustic and electromagnetic scattering. The design of efficient numerical methods for the forward problem, in which the scattered field is computed from known geometric configurations is very challenging due to the multiscale nature of the problems. Even more challenging are inverse problems where material parameters and configurations have to be determined from measurements in conjunction with the forward problem. This book contains review articles covering several state-of-the-art numerical methods for both forward and inverse problems.

It records the achievements of Workshop 3 “Wave Propagation and Scattering, Inverse Problems and Applications in Energy and the Environment” that brought together key numerical mathematicians with an interest in analysis and computation of wave propagation problems with practitioners from engineering and industry.

LMS meeting on "Sparse Regularisation for Inverse Problems"

Nov 2, 2013. Inverse problems appear in many situations in physics, engineering, biology and medicine. The main mathematical problem is the well (ill) – posedness of the inversion process. Indeed, in practice most inverse problems are ill-posed in terms of non-uniqueness or lack of stability of the inversion. This one-day meeting on 7 February 2014 is the first LMS meeting on inverse problems (in a series of four in 2014) that brings together UK researchers who work on advancing the field of inverse problems, both from a theoretical and from an applied point of view.

The meeting will concentrate on sparse regularisation of inverse problems. Regularisation is one major technique for the solution of ill-posed inverse problems. It imposes sufficient constraints on the solution to allow for a stable inversion. In recent years ideas from compressed sensing and sparse reconstruction have entered inverse problems research with the development of inversion models that feature a regularisation which imposes certain sparsity constraints on the solution. In particular, this meeting will concentrate around the major themes:

  • Modelling of sparsity
  • Non-smooth regularisation and geometric priors
  • Sparse sampling
  • Sparse regularisation in practice

This event is funded by the London Mathematical Society.

Speakers: Invited speakers will include:

Robert Aykroyd (University of Leeds), UK
Martin Benning (University of Cambridge), UK
Marta Betcke (UCL), UK
Martin Burger (University of Münster), Germany
Ke Chen (University of Liverpool), UK
Paul Childs (Gould Research Center, Schlumberger, Cambridge), UK
Anders Hansen (University of Cambridge), UK

The application deadline is 20 January 2014. For more information see

Workshop on Parameter Estimation and Inverse Modelling for Atmospheric Composition

Oct 14, 2013. From 22 to 24 October 2013 ECMWF is organizing a workshop on Parameter Estimation and Inverse Modelling for Atmospheric Composition.

The modelling and data assimilation of atmospheric composition differs in several ways from the modelling and data assimilation for numerical weather prediction, such as the atmospheric chemistry, available observations, and the greater importance of mass conservation for long-lived tracers. However, another important aspect is the significance of the boundary conditions. Anthropogenic emissions, greenhouse gas surface fluxes, wild fire emissions, and volcanic eruptions form a significant part of the assimilation and forecasting problem, which can therefore not really be treated as an initial condition problem with a (almost) perfect model. The aim of the workshop is to explore the options to optimally define the boundary conditions in a near-real-time 4D-var data assimilation system for atmospheric composition. There is significant experience in the research community with flux inversions, estimating volcanic emissions, and optimizing emission estimates. An important question for the workshop is therefore how to combine existing forward models with inverse modelling techniques, e.g., through parameter estimation, in an operational environment.

The workshop is approaching fast, but we still have some room for additional participants. Full information (including programme) can be found at Webpage. If you would be interested to participate in this exciting workshop, please register through the web site before the end of this week.

For the organizing committee, Richard Engelen

Full announcement

Neural population models (NPMs) describe the overall behaviour of large ensembles of neurons. Various names have been used for this general approach according to mathematical and conceptual detail: neural mass models, mean field models, neural field models, cortical field theory, etc. Since not all neurons are modelled individually, a distinct advantage of these lumped models is the reduction in dimensionality of both the parameter and variable space, which reduces computation time and makes possible sophisticated mathematical analyses of the model?s behaviour as well as their application to experimental data. Nevertheless, NPMs retain their biological interpretability, allowing researchers to investigate a wide range of brain function in health and disease, as well as the effects of drugs and other extraneous influences.

Current non-invasive neuroimaging methods such as EEG, fMRI and MEG measure in various ways the activity of sizable groups of neurons, making their data a natural target for NPMs. Furthermore, thanks to the speed with which NPMs can be evaluated one can computationally match the ability of these modalities to record the activity of entire brains. In combination with rapid experimental progress in determining the large scale connectivity (the connectome), this is leading to novel NPM-based methods for the modelling of partial or even full brain networks. Typically such models are characterized by time delays via signal propagation along connecting fibres with NPMs as network nodes. They promise to make NPMs the tool of choice for neuroimaging analysis in the future.

Topics of interest for this thematic series include but are not limited to the following advances in neural population modelling:

  1. the inclusion of neural mechanisms such as spike rate adaptation or bursting
  2. the effects of higher order statistics on the dynamics
  3. the formal and/or computational correspondence between microscopic and macroscopic models
  4. adapting models for different regions of the brain
  5. describing pathologies and drug effects
  6. the development of new analytic tools for these systems
  7. determining the effects of connectivity on dynamics
  8. building partial and full brain networks
  9. studying large scale brain dynamics in health and disease
  10. addressing cognition through associated brain processes

Authors are cordially invited to submit original research papers on novel techniques, theoretical analyses and simulations, as well as applications to experiment and data analysis, of recent developments in neural population models and their networks.

Recent Progress in Mathematical and Numerical Analysis of Inverse Problems

Oct 7, 2013. The analysis of inverse problems belongs to one of the fastest growing areas in applied mathematics. Inverse problems are encountered in several areas of applied sciences such as biomedical engineering and imaging, geosciences, remote sensing, financial modelling and non-destructive material evaluation.They arise in many practical situations when difficulties are experienced in measuring causal features of a given phenomenon. Solving the associated inverse problem is thus an attempt to construct from its actual observation, the equations which give rise to it.

There is a large number of mathematical and computational difficulties associated to the analysis of inverse problems. One of the great challenges of solving inverse problems lies in the fact that they might be ill-posed or non linear.

The aim of this conference is to stimulate discussions on mathematical and computational challenges of inverse problems, and namely on problems arising in the analysis of

inverse problems with internal measurements, which play an important role in detection problems encountered in tomography, imaging and photoacoustics. control methods in inverse problems allowing to retrieve singular sources in the wave equation. inverse conductivity problems which may now be treated with partial and local Dirichlet-to-Neumann maps; application of Carleman inequalities to the study of inverse problems. The steering committee planned to dedicate a significant part of the financial support assigned to this conference for inviting young researchers working in the field of the inverse problems in order to allow them to interact with numerous recognized actors in this domain.
