The ensemble Kalman filter (EnKF) and its many variants have been proven effective for data assimilation in large models, including those in atmospheric, oceanic, hydrologic, and petroleum reservoir systems. By bringing together technical experts, practitioners, researchers and students for presentations and informal interchange of information, we aim to share research results and suggest important challenges that have yet to be addressed.

Venue

Venue: May 2 - 5, Thon Hotel Sandven, Norheimsund, Norway

Program

Workshop program

The cultural even/excursion will likely consist of a hike to the Steindal waterfall (with an optional extension with some beautiful vistas), and a visit to a local apple cider farm. Another possibility is a visit to the Hardanger Fartøyvernsenter (Maritime center).

Background

The EnKF is a data assimilation method was co-invented and has been continuously developed by researchers at NORCE and NERSC. In the past two decades, the EnKF and related “ensemble” methods have been established as a school of viable and popular methods for data assimilation in very large models, and have made immense impacts on the advancements of various disciplines and promoted value creations for relevant industries.

Purpose

Although the basic concept ensemble methods is straightforward, successful practical implementations often require modifications that are problem-specific. By bringing together experts from diverse areas, we aim to explore the bases and connections among EnKF-related methods that are proven to work in different environments, so that the resulting applications are more robust and efficient. Other than the aspect of practical applications, this workshop also aims to exchange and communicate novel research ideas, methods, algorithms and/or workflows that have the potential of further improving the performance of EnKF and its related methods.

History

The first EnKF workshop took place in Voss (Norway) in 2006. Since then, the EnKF workshop has been held annually (except for a disruption in 2020 due to COVID-19). The EnKF workshop has always accommodated participants coming from diverse scientific disciplines (e.g., meteorology, oceanography, hydrology, to name a few). The communication and exchange of scientific progresses and advancements have led to even more fruitful discussions and raised the scientific quality of the workshop to a very high level. As such, the annual international EnKF workshop has now become one of the most influential events within the data assimilation community.

Abstract submission

Changes in format:

The following changes are made compared to recent workshops.

  • Physical attendance only. No videoconferencing.
  • Posters will have significantly more prominence, with much more time dedicated to the poster sessions (see program). The number of talks is reduced from the previous years’ average of about 40 to 24, while the number of posters will be increased from less than 10 to 24.
  • Talks are limited to a run time of 20 min (40 for invited), followed by maybe 10 min. Q&A.
  • At the end of each day there will be 30 min. dedicated to a plenary discussion around a selected though-provoking talk or subject.

Submissions

Deadline: Feb 5, 14pm CET. This workshop does not take paper submission or publish conference proceedings.

Non-presenting attendees should also fill in the form below, leaving the presentation fields empty.

Scientific committee

  • NORCE: Geir Evensen, Dean Oliver, Patrick N. Raanes
  • NERSC: Laurent Bertino
  • Equinor: Remus Hanea

The scientific committee will convene to discuss submissions in February. You will be notified of the decision shortly afterwards, as well as provided with a link to perform the payment of the registration fee, which we estimate at € 780 and will cover the hotel room and meals for 3 nights, a cultural excursion, and the Bergen-Norheimsund round trip.
