Document overturning variables

[Sougata18]

Hello everyone! I have been trying to run one of the basic setups available in Versos, i.e. , the gloabl_1deg setup on my PC. But each time I try to run, its showing a "killed" message in the terminal. My PC has 8 GB RAM ; Is it too low to run the setup on my PC?

Also I would like to know what the output variable names actually mean. There are some variables for example the "bolus_depth" and "bolus_iso" from the global_4deg setup which inspite of having the same coordinates and attributes (i.e., meridional transport), represent different things. I looked into the official documentation but it has description for only model variables.
Thanks for any kind of help!

Yes, I would recommend at least 12 GB of memory. You might be able to get by with less by using JAX and picking a different equation of state. Otherwise you can use global_flexible and set it to a resolution that is slightly above 1 degree.

You are right that the overturning variables are currently undocumented. To be honest I haven't looked at most of the outputs myself (just ported them from PyOM and ensured that the output matches) except the vertical streamfunction.

It looks like bolus_iso is the bolus (eddy-induced) meridional transport in isopycnal coordinates and bolus_depth that in z-coordinates. But I don't know the details, for example why you need both and how exactly they differ. If someone who knows more about this can contribute a better explanation I'd be grateful :)

Thanks a lot for the info!
