Partanen, A.-I.; Kokkola, H. (2012): Direct and indirect effects of sea spray geoengineering and the role of injected particle size

Partanen, Antti-Ilari; Kokkola, Harri; Romakkaniemi, Sami; Kerminen, Veli-Matti; Lehtinen, Kari E. J.; Bergman, Tommi et al. (2012): Direct and indirect effects of sea spray geoengineering and the role of injected particle size. In: J. Geophys. Res 117 (D2).. doi:10.1029/2011JD016428 (final paper)

"The aerosol direct effect of sea spray geoengineering is not insignificant - Cloud modification was most efficient when the injected particles were small - There are large uncertainties in the efficiency of sea spray geoengineering"
