That would get you pretty close. I’m not sure if he makes these publicly available...</div><div><br class=""></div><div>I use rbcs to force internal tides in situations like this to allow the sponge layer to have lateral variability. i.e. you force a perfect internal tide in the sponge layer versus one value that you would get in a normal obcs sponge layer because you usually want your sponge to be substantial compared to internal tide wavelength. (see the setup in 10.1175/JPO-D-16-0061.1, and somewhat messily: <a href="http://web.uvic.ca/~jklymak/ttide15/" class="">http://web.uvic.ca/~jklymak/ttide15/</a> if you want the set up).</div><div><br class=""></div><div>Cheers, Jody <br class=""><div><br class=""></div></div><br class=""><div class="">
