Comments on observed differences: Below we summarize the notable changes caused by specific updates.

Scale DICE-Africa emissions to address errors in inventory

This update contributes to changes in BC and OC concentrations over and just downwind of Africa. Slight differences can also be seen over Africa in the emission maps. The impact on the inventory emission totals are included below.
