<p class="MsoNormal">Hi Dan,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have a flux-forced configuration for ECCO V4 Release 4 that I’ll make available in a week or so. This configuration reads in the pre-computed v4r4 forcing from files, as opposed to using the bulk formulae. Net heat flux, wind stress,
freshwater flux and a few others are part of the control variables. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If you were to find a flux-forced configuration for ECCO V4 Release 3, it is available at https://github.com/owang01/ECCO-v4-Configurations/tree/master/devel/fluxforced/.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I also plan to make a tutorial for doing an adjoint reconstruction using the adjoint sensitivity. This tutorial will be provided as a Jupyter notebook.

<p class="MsoNormal">Is there an ECCOv4 configuration/solution that avoids using the bulk formulae? That is, a solution that uses net heat flux as a control variable?<o:p></o:p></p>

<p class="MsoNormal">For context: I would like to attempt an adjoint reconstruction using net heat flux and wind stress. However, if we use the bulk formulae, there is a risk of double-counting (as pointed out by Yavor Kostov). Gael Forget suggested that avoiding
the bulk formulae altogether could be a promising way to start.<o:p></o:p></p>
