= PDAF_deallocate = 

This page documents the routine `PDAF_deallocate` of PDAF, which was introduced with PDAF V1.13. 

|| With PDAF V3.1 we introduced [wiki:PDAF_finalize] and recommend to use this routine instead. ||

This routine deallocates the big internal arrays of PDAF to clean up memory at the end of a data assimilation simulation. It further finalized the MPI parallelization if it was initilize by PDAF.

The interface is the following:
{{{
SUBROUTINE PDAF_deallocate()
}}}
Thus, it was no arguments.

Note:
 * Usually, we call this routine in the interface user routine `finalize_pdaf`
 * Calling `PDAF_deallocate` is not mandatory. Usually, the operating system cleans up all used memory by itself when the program stops. However, it's good practice to explicitly clean up the memory.
