Full-Pos is the nickname of the Post-Processing package in the Arpege/Ifs/Aladin software.

– FullPOS is a powerful and sophisticated post-processing package. It is intended to be used for operation and research as well.

– FullPOS has two main parts : the vertical interpolations, then the horizontal interpolations. In between, a spectral treatment is sometimes possible for the dynamic fields.
