Hi Corinne,

Good question!  Given that we're bound to be using different solubility
fractions (mine are a climatology variable in space after Fan et al,
2006), I'd prefer the definition be renamed to "Surface downward net
flux of dissolved iron", unless there are models that include subsurface
dissolution of dust, in which case I would suggest we add another
variable called "Surface downward net flux of total iron".  Though I
would not want to fill this field for my model in order to avoid confusion.

Cheers, John
