Abstract
Data assimilation is the process of using measured data to correct the state of a mathematical model. This report documents the data assimilation process implemented in the ocean model system SINMOD, and the tests that have been run in the ELMO project. The report describes the choice of the EnOI assimilation method, its implementation in SINMOD, the input layer for providing measurement data to the model, and two test cases where the model has been run with assimilation of current data.
