Modeling marine biogenic aerosol precursors in the Arctic Ocean
The climate radiative effect of Arctic clouds depends on the presence of liquid or ice as cloud phase, which, among other things, is determined by the abundance of aerosols acting as cloud condensation or ice nuclei. Biogenic aerosols originate from local phytoplankton production in leads or open wa...
