    122122The PDAF initialization can be tested by compiling the program and executing it. The Makefile of the model has to be extended to include the additional files.  The core part of PDAF can be compiled separately as a library and can then simply be linked to the model code. This is the strategy followed in the PDAF-package.

    124 At this stage it will not be meaningful to perform an actual integration. However, one can test if the initialization in PDAF_init is sucessful and if the ensemble array is correctly initialized.
