|
|
!! ** Method : set all intent(out) argument to a proper value
|

!! Here C1D_PAPA configuration :

!! Rectangular 3x3 domain
|
|
!! - Located at 150E-50N
|
|
!! - a constant horizontal resolution
|
|
!!
|
|
!! ** Action : - define longitude & latitude of t-, u-, v- and f-points (in degrees)
|
|
!! - define coriolis parameter at f-point if the domain in not on the sphere
|
|
!! - define i- & j-scale factors at t-, u-, v- and f-points (in meters)
|
|
!! - define u- & v-surfaces (if gridsize reduction is used in some straits) (in m2)
