<font face="Times New Roman, Times, serif">Dear all,<br>
<br>
I would like to restart a simulation originally performed without
the biogeochemical packages by activating them (thus including
PTRACERS, GCHEM and DIC). Since there are no some of the needed
pickups (namely, pickup_cpl and pickup_aimCo2), I have created
them by performing a simulation that starts from nIter0=0. My idea
is to use such pickups to restart my simulation, is this the right
procedure?<br>
<br>
Doing like this, I obtain reasonable values for the tracers if I
activate DIC_BOUNDS in order to avoid out-of-range pH values.<br>
<br>
Since I am performing paleo-climate simulations with huge
uncertainties on the concentrations of the different tracers, I am
wondering: <br>
<br>
1. Is it correct to set PTRACERS_ref to zero values and start from
PTRACERS_Iter0=nIter0 without any initial file? (if I understand
well, all fields would be initialised to 0 in this case)<br>
2. Is the model very sensitive to PTRACERS_EvPrRn? Or is it only
necessary to give a certain value for allowing
dilution/concentration? Which value?<br>
3. Which is the role of the input files in data.dic (ice, wind,
silica, atmospheric pressure)? Should they replace pickup files?<br>
<br>
Thanks in advance for any suggestion!<br>
<br>
Best,<br>
Charline<br>
