EMPIRE: Employing MPI for Researching Ensembles


    EMPIRE logo

A model developer walks into a bar and sees a data assimilator. "I have a model which I want to assimilate data into", says the model developer. "Add the EMPIRE functionality to your model and come back and buy me a drink" replies the data assimilator.

EMPIRE is the name given to a way of changing the source code of a dynamical model so that it can interface with sequential data assimilation methods.

EMPIRE should be one of the quickest and easiest ways in which to modify the source code of the model to use data assimilation.
