Dataset associated with "A mineralogy-based anthropogenic combustion-iron emission inventory"

Contains yearly-averaged total and soluble iron concentration and deposition fields along with separate variables for dust and combustion.The atmospheric supply of iron can modulate ocean biogeochemistry, due to its key role in global nitrogen and carbon cycles, with current estimates predicting up to 20% of global ocean net primary productivity depending on this source. We estimate anthropogenic iron using a detailed technology-based estimation method, resolve it into mineral components, and model soluble iron emissions using various available solubility representation methods including mineralogy. Including metal smelting as a source that emits about 75% of anthropogenic iron, we show that anthropogenic iron emissions are up to 10 times higher in the fine aerosol fraction (
