Units

[davidanthoff]

The units are quite inconsistent. The following list is just from looking at the files in the data folder:

• we seem to mix and match cases where we just specify units of measure, and others where we specify what we measure in the unit. For example we have "Mtonne/year", that doesn't specify megatonnes of what gas?
• growth rates are sometimes expressed as %, sometimes as %/year.
• We use $million, maybe we should encode the price level there?
• We use degreeC, but really it is degree C above pre-industrial...

We probably don't have to fix all of these now, this is more of an aesthetic point. But maybe we can at least make sure that any flow variable includes some info about the duration (i.e. %/year vs e.g. %/timestep).
