Show morePrevious coupled experiments assimilated in a "weakly-coupled" configuration, where a filter was run independently in each of the coupled components. The new implementation combines state information from all coupled components into a single state in one filter. Existing single-component code is reused in the coupled configuration, reducing the need for duplicate code or reimplementation. Forward operators can be developed that combine information from multiple components. Increments from one component can apply directly to other components. Many outstanding issues remain and will be discussed. Show less
