The assimilation package “DAPPER” – Data Assimilation with Python: a Package for Experimental Research – is easy to use. With this, different data assimilation methods can be compared, and are applicable both in research and for educational purposes.
The program package “Fortran90 EnKF” is based on the Ensemble-Kalman filter method (EnKF), a unique data assimilation method developed at the Nansen Center. The package is tailored to large amounts of data for use in ocean models. At the Nansen Center, it is used when preparing forecasts for the ocean, sea ice, and climate.
