Avoiding wrong inputs

I thought about your question about how we could make sure that users provide parameters in the right unit. We could make a test and provide a warning if, say:

• DIC is outside the range 140e-6 to 3000e-6
• TA is outside the range 600e-6 to 3000e-6
• Sit is outside the range 0 to 300e-6
• Pt is outside the range 0 to 5e-6

These ranges are estimates based on GLODAP v2.

What do you think?

I suggest to widen the ranges for DIC and TA so as to be more inclusive of estuaries and extremes in coastal and marginal seas, tide pools, etc.

For the low end, I would suggest zero for both DIC and TA. For the high end, my point was only to catch those gross errors where people used the wrong units, e.g., mmol/kg or umol/kg instead of mol/kg. For that objective, perhaps you could just position the high limit midway between 3000e-6 and 3000e-3.

I meant about half way between 3000e-6 and 3000e-3 on a log scale, i.e.,

3000e-(4.5) = 0.095
