Timeseries of the Black Carbon (BC) / Carbon Monoxide (CO) / Sulphate Sulphur (SO4-S) concentration due to transport from anthropogenic sources. The values, in ug/m3, has to be considered as the anomaly in concentration due to sources encountered 0.25, 1, 7, 10, or 30 days before, with respect to an existing older background (not included in this model output). We use here the emissions from the ECLIPSE v6b inventories. (https://iiasa.ac.at/web/home/research/researchPrograms/air/ECLIPSEv6b.html). 

The level, 100m or 3000m, refers to the thickness of the layer, above ground level, in which the air masses are considered to interact with the emissions. E.g. in the 100m file, the trajectories are considered to encounter a source only when traveling below 100 m.
