Dear Martin It was because of this point that tendency of content was adopted:

It makes sense that a net surface flux could go either way. For other quantities, we have defined standard names of upward and downward fluxes as alternatives, so people can use whichever sign they want. To make it clearer, we could say surface_net_upward or surface_net_downward, as we do for radiation. My question is whether this is the best way to name surface species fluxes, or should they be called tendency of content due to net surface flux. The latter would be consistent with other chemical names, but looks a bit obscure to me - however, either would work.
