Data sets

Back-trajectory data were calculated from the NOAA HYSPLIT model NOAA http://ready.arl.noaa.gov/HYSPLIT.php

Short summary

We investigated mixing states and morphological features of soot-containing particles, by using water-dialysis analysis in remote ocean areas over the southern Indian Ocean and the Southern Ocean. Most particles were water-soluble. However, rarely were particles (2.1 % of particles on a TEM sample at a maximum) found to contain insoluble residuals with the characteristic soot shape.
