#2606 new Request

improve initalization with data ( dtatsd.F90)

Reported by: cbricaud Owned by: systeam
Priority: low Milestone: 2021 WP
Component: TOP Version: trunk
Severity: minor Keywords:



dtatst is used to read T&S data. These data can be used to initialize the model and/or make damping


It implies that the same data are used for initialization and damping: a second dtatsd routine could be add to allow initialization and damping with 2 differents data sets.

U&V&SSh could also be initialized. dtauvd.F90 should be refresh and generalized to all configurations ( not only for 1D)

subject already partly discuss here : ticket #2539 with possible code example to do it (ISOMIP+ or DRAKKAR)

Not too sure whether this is also worth considering: ticket #1579 (very old now, but still open)
I have a 4.0 patch which will perform a linear interpolation of initial conditions (or damping conditions) onto the native grid. It was primarily aimed replacing the IF( ln_sco ) THEN block in dtatsd.F90 as this had so many caveats attached to it.
Happy to discuss...
