<p>Dear Kunal, <br>
</p>
<p>to some extent yes. There is a setting of the model where calcite
dissolution is calculated as a function of calcite saturation
state, which is switched on by setting CAR_DISS=.true. in
DIC_OPTIONS.h. That was originally put into the model by Kasten
Friis. <br>
</p>
<p>In that case, the saturation of CaCO3 is calculated at every
depth, which implies a calculation of the full carbonate
chemistry, including the pressure dependence of the equilibrium
constants. Have a look into the routine calcite_saturation.F if
you want to understand how. <br>
</p>
<p>Note, hoewever, that it is computationally expensive to do so,
and because of that the standard setting is not to calculate this
at every time step, but only every now and then. <br>
</p>
<p>I hope that helps to get you started. <br>
</p>
<p>Cheers, Christoph<br>

<div>Dear MITgcm users,</div>
<div><br>
</div>
<div>My question pertains towards the DIC package, which
provides pH, pCO2, CO2 flux, etc</div>
<div>as 'surface diagnostics'. As the name suggests, it gives
output only at surface level.<br>
</div>
<div><br>
</div>
<div>Is there a way I can simulate these parameters in depth as
well? Any suggestions?</div>
