IICWG/S4D workshop 2008 (Copenhagen)

Document Actions
A joint International Ice Charting Working Group (IICWG) and SEARCH for DAMOCLES (S4D) workshop on Assimilation of data into models of the Arctic at the Danish Meteorological Institute (DMI) in Copenhagen from October 15th to 17th, 2008.

Agenda

DAY 1
 
 
 

9:00
Welcome and logistics, Goals, Introduction

Leif Toudal Pedersen,  Lars-Anders Breivik, Tom  Carrieres, Frank Kauker
9:30
Validation of a regional coupled ocean/sea ice model in Nares Strait

Till Rasmussen
10:00
Development of operational coupled sea ice and ocean model at DMI
Stiig Wilkenskjeld
10:15
Canceled
 
10:45
Break
 
11:15
Parameter sensitivity to assimilation of different data in a sea-ice model using the Ensemble Kalman Filter
Christof Koenig Beatty
11:45
 Assimilation of  sea ice observations in a coupled ocean sea ice state estimate of the Labrador Sea using the adjoint method
Ian Fenty
12:15
Lunch
 
13:30
 Discussion: Is there an optimal ice model for all purposes or classes of models that are more appropriate to ice services or climate modeling. How close are we to having a linearized version of a coupled ice-ocean model?
Moderator: Tom Carrieres
14:30
Assimilation of observed and unobserved ocean and sea ice
Lars Axell
15:00
Break

 
15:30
Variational assimilation of hydrographic and ice concentration observations into a coupled ocean sea ice model of the Arctic
Thomas Kaminski
15:45

Quantitative Network Design

Thomas Kaminski
16:00
Adjoint analysis of the summer 2007 low in Arctic sea-ice area

Frank Kauker
16:30

Discussion:  Strengths and weaknesses of DA techniques and how each can benefit from the other.
Moderator: Mark Buehner
19:30
Workshop Dinner at the Copenhagen Planetarium

 
DAY 2

 
 
9:00

An overview of some Environment Canada sea ice data assimilation projects
Tom Carrieres
9:30
Sea ice thickness categories and their error covariances for assimilation with a three-dimensional variational data assimilation system
Alain Caya
10:00

Towards the use of high-resolution remote sensing data in a three-dimensional variational analysis system: A collaboration with OSI-SAF
Mark Buehner
10:30

Break

 
11:00

Assessment of the ECCO2 regional optimized solution in the Arctic
An T. Nguyen
11:30

Discussion: Background error estimation, use of observations, etc. What are main      sources of sea-ice background error (i.e. 12-24h forecasts):atmospheric forcing error? ocean forcing error? sciences of ice model? uncertain parameters (drag coeff., yield curve)? What fraction of the error can be explained by: ice displacement errors? melt/growth errors?

Moderator: Lars-Anders Breivik
12:30

Lunch
