The packages implements various data assimilation methods:

  • (Extended) Kalman Filter
  • Incremental 4D-Var
  • Ensemble Square Root Filter (EnSRF)
  • Ensemble Square Root Filter with serial processing of the observations (serialEnSRF)
  • Ensemble Transform Kalman Filter (ETKF)
  • Ensemble Transform Kalman Filter (EAKF)
  • Singular Evolutive Interpolated Kalman filter (SEIK)
  • Error-subspace Transform Kalman Filter (ESTKF)
  • Ensemble Kalman Filter (EnKF)

The Julia code is ported from the Matlab/Octave code generated in the frame of the Sangoma project (http://data-assimilation.net/).

Example

An example of using to package is available as a jupyter-notebook.
