Interface routine called from the model during the ! forecast of each ensemble state to transfer data ! from the model to PDAF and to perform the analysis ! step. ! ! This routine provides the simplified interface ! where names of user-provided subroutines are ! fixed. It simply calls the routine with the ! full interface using pre-defined routine names. ! ! The routine supports all global filters. ! ! ! This is a core routine of PDAF and ! should not be changed by the user ! ! ! !REVISION HISTORY: ! 2024-08 - Lars Nerger - Initial code !
