Dear Paul I think this is more systematic than you suspect!
* It is only sea level change with has _change at the end. These quantities only have meaning as "change", not as an absolute quantity. So the "change" there is part of the name of the basic quantity. * change_[over_X_]in is a prefix which indicates the difference in quantity between two circumstances, such as two times. * tendency_in is a prefix which indicates the time-derivative of the quantity. It has the units of the quantity multiplied by reciprocal time. The period over which a time-change or tendency is calculated is indicated by the time bounds or climatological bounds. If it's an instantaneous tendency, it applies at the time coordinate. This distinction is indicated by cell_methods.
