    • Data assimilation for coastal zone monitoring and forecasting 

      Evensen, Geir; Drange, Helge (Elsevier oceanography series. (EuroGOOS publication no. 7), Chapter, 1997)

    • Inverse Methods and Data Assimilation in Nonlinear Ocean Models 

      Evensen, Geir (Journal article, 1994-10-01)
      An overview is given of the current status of inverse methods and data assimilation for nonlinear ocean models. The inverse theory for time dependent dynamical models is formulated and the most promising solution methods ...

    • Ocean data assimilation systems for GODAE 

      Cummings, James; Bertino, Laurent; Brasseur, Pierre; Fukumori, Ichiro; Kamachi, Masafumi; Martin, Matthew J.; Mogensen, Kristian; Oke, Peter; Testut, Charles Emmanuel; Verron, Jaques; Weaver, Anthony (Oceanography, GODAE Special issue feature, Journal article, 2009-09)
      Ocean data assimilation has matured to the point that observations are now routinely combined with model forecasts to produce a variety of ocean products. Approaches to ocean data assimilation vary widely both in terms of ...

    • Parameter Estimation Solving a Weak Constraint Variational Formulation for an Ekman Model 

      Eknes, Mette; Evensen, Geir (Journal article, 1997-06-15)
      A weak constraint variational formulation is used for inverse calculations and parameter estimation in a one-dimensional Ekman model. When parameters in the model are allowed to contain errors, the inverse problem becomes ...
