    1919There are two possibilities to build a data assimilation system
    2020 1. '''Offline mode:''' The model is executed separately from the assimilation/filter code. Output files from the model are used as inputs for the assimilation program.
    21  1. '''Online mode:''' The model code is extended by calls to PDAF core routines. A single executable is compiled. Whlie running this single executable the necessary ensemble integrations and the actualy assimilation is performed.

    2222PDAF supports both the online and offline modes. Generally, we recommend to use the online mode because it is more efficient on parallel computers. However, the required coding is simpler for the offline than the online mode.
