Description
Introduce the modified Leap-Frog Robert-Asselin filter to fit the one presented in Leclair and Madec Ocean Modelling (2009).
The main remaining modifications concern :
(1) forcing terms as a mean between time step n-1/2 and n+1/2 (sbcmod)
(2) Asselin filter: remove the forcing from the filter (dynnxt, tranxt, traqsr)
(3) semi-implicit hydrostatic pressure gradient : change the coefficients to take into account the Asselin filter parameter (tranxt)
This update is part of the LOCEAN.8 task (Update of the ocean physics) due by June 25th
