This data set allows to determine the degree on how much black carbon is potentially taken up by low-level Arctic clouds. The unique long data coverage makes the data suitable for the evaluation of black carbon concentrations as well as black carbon scavenging within Earth system models.\r\n\r\nBlack carbon particles originate from incomplete combustion such as emissions from cars, ships, industry or forest fires. These particles can be transported to the Arctic atmosphere, where they can have an impact on climate by e.g. scattering and absorbing solar radiation or by influencing clouds through acting as nuclei for the formation of cloud droplets.","citations":"Zieger P, Heslin-Rees, D, Karlsson, L, Koike, M, Modini, R, Krejci, R (2023) Black carbon scavenging by low-level Arctic clouds.
