A - The set-up routines

Damien Declat – CERFACS – 20/10/03 TR/CMGC/03/103 The aim of this document is to detail the interactions between the PSMILe and the transformer. First we will detail the different routines that should be used inside the PSMILe routines, then the transformer logic and finally an example of interaction between the transformer and two component PSMILe. The PSMILe_trs routines should be used inside the PSMILe to communicate informations to the transformer or to search for neighbors considering a target and a source epios (Annex 1 gives a short description of the 'epio' notion). Note: we realize that it would be necessary to take into account the ids of the source and target grids in the psmile_trs call to insure uniqueness in the transformer tables. These parameters will be added later. A-The setup routines The following routines correspond to the setup and should be used below the PRISM_Enddef routine. Purpose: this routine transfers the EPIO (the points involved in an interpolation computation between one process of the source component and one process of the target component) that has been calculated inside the PSMILe. This EPIO can be a source EPIO or a target EPIO. As we deal with the 2D routines, the transferred arrays are the latitudes, the longitudes and the mask.
