Note in all cases except code groups can be expanded and contracted to make the model easier to work with

Specific atmospheric curves can be selected. See help on calibration curves.
An exponential reservoir time constant can be enetered where turnover is slow relative to the resolution.
Marine components can be entered in any proportion (select 100% for fully marine). You will need to set a ΔR offset for local effects. See help on calibration curves for links to database of values.
