That link could do to provide a few more details.
Dimethyl sulphide is implicated in cloud formation:
http://en.wikipedia.org/wiki/Dimethyl_sulfide#Natural_occurrence
http://homepages.see.leeds.ac.uk/~eardvs/papers/korhonen08b.pdf
It isn't clear if the link you provided is talking about any albedo effect from the sulphide particles, or if it is also taking impact on cloud formation into account - as clouds play a significant role in global albedo? (not to mention being nice if you want rain).
The abstract of the paper the link goes to (
http://www.nature.com/nclimate/journal/vaop/ncurrent/full/nclimate1981.html
) does not appear to mention impact on cloud formation, so I'm going to assume the albedo effect quoted is only for the direct effect of changing the amount of sulphide particles and doesn't consider knock on impact on cloud formation (until or unless someone corrects me).
