Accounting for this is particularly important to obtain accurate representation of tides at the global scale. This can be achieved in numerical models by adding an additionnal term to the existing astronomical potential. The exact computation of this term (which depends on the model tidal solution) is particularly expensive on a numerical point of view and is not part of this implementation. We will provide here the proper interface in the tidal module and user interface as well to read the SAL potential from external models (TPXO for instance). The possibility to use a simple "linear" approximation from the sea level anomaly, a commonly used alternative, will also be implemented. 33 34 Self Attraction and Loading effects represent the modification by tides of the earth gravity field through mass redistribution.
