Studied atmospheric circulation on Mars

19.06.2018

13th EnKF workshop in Bergen: "It was the first time for the EnKF workshop to witness the application of an ensemble Kalman filter (EnKF) to study atmospheric circulation on Mars"; Xiaodong Luo from IRIS points out.

Research Director at IRIS, Randi Valestrand explains that there has been a long tradition for IRIS, Uni-Research-CIPR, NERSC and Equinor to jointly organize the annual international workshop on ensemble based data assimilation. This year the 13th workshop took place in Bergen City from 28-30 May, with fantastic weather.

Sightseeing in Bergen
During the two conference evenings the delegates enjoyed a boat trip to a fish restaurant on an island and visited the Fløyen restaurant on top of one of Bergen’s surrounding mountains.  

51 participants
The workshop aims to bring together researchers, practitioners and younger-generation students to present their recent research progress and applications. This year the workshop attracted 51 participants with diverse background, we had several talks on methodological developments, and, applications on a wide range such as data assimilation used for: ocean models, earth systems models for climate predictions, atmosphere-land subsurface models, model for blood flow in the brain, tidal models, ocean and biochemical models, full waveform inversion, monitoring CO2 injection, 4D seismic history matching and several petroleum data assimilation problems. 

Atmospheric circulation on Mars
During the workshop we registered some new records. For the very first time the workshop hosted a speaker from South Korea and the workshop had a significant number of participants from outside of Europe.

​"It was the first time for the workshop to witness the application of an ensemble Kalman filter (EnKF) to study atmospheric circulation on Mars. We especially want to thank this years invited speakers"; Xiaodong Luo points out:
 
  • Nancy Nichols; University of Reading, U.K.; "Diagnosis, conditioning and regularization of error covariance matrices in data assimilation​"
  • Svetlana Dubinkina; Centrum Wiskunde & Informatica (CWI); Amsterdam, Netherlands; "Relevance of conservation laws for an Ensemble Kalman Filter"
  • Harrie-Jan Hendricks-Franssen; Forschungszentrum Jülich, Jülich, Germany; "Coupled data assimilation for the athmosphere-land surface-subsurface models"
  • Yan Chen; Total GRC, Aberdeen, UK; "Uncertainty representation in reservoir history matching with ensemble methods: how complex does a model have to be?” ​
  • Remus Hanea, Equinor, Norway: "Transgress the base case"
 
IRIS was well represented, with five oral presentations two posters. Talks and posters will be available from our EnKF website as we get permission. Finally, we would like to thank our co-organizers again, and, also thank our sponsors: Equinor, the Research Council of Norway’s IKTPLUSS events support and the Petromaks2 project DIGIRES
