 === Description
+1) Simplify/clean the actual split-explicit procedure: 
+- Remove " centred integration" of barotropic mode (ln_bt_fw=F), which is only relevant with LF-RA and not compatible with AGRIF. 
+- Set initialization of filtering weights at initialization step (maybe not relevant to do so if any adaptive time stepping procedure is ever implemented).
+- Add time indexes (4 levels) to barotropic instantaneous arrays (AB3-AM4 time stepping)
 
-{{{#!box width=25em help
-Describe the goal of development and the methodology, \\
-add reference documents or publications if relevant.
+2) Refactorize dynspg_ts module:
+- Extract a single external step into a stp_2D routine
+- Same for barotropic to baroclinic forcing term: prep_stp_2D

+! Set barotropic forcing (incl. 3d to 2d forcing)
