For those of you haven't seen this yet, there's an interesting recent study in Atmospheric Chemistry & Physics ( http://www.atmos-chem-phys.net/10/4133/2010/acp-10-4133-2010.pdf) assessing the impacts of marine cloud albedo enhancement using a global aerosol transport model. Among the takeaways from the study:
- Changes in cloud drop number concentration (CDNC) were small (20% or less), and in one of the four regions studied (North Pacific, as well as off the coast of Chile), even negative. The authors argue this was attributable to the fact that particles suppress in-cloud supersaturation, preventing existing aerosol particles from forming cloud drops; - A run with 5x higher emissions showed much greater CDNC changes, but the median was still below that found in previous studies; - The study showed substantial differences in CDNC between and within regions, in distinction to far more regional homogeneity in previous studies It would be interesting to hear the take of some of the folks on this list with expertise in this context. wil -- Dr. Wil Burns, Editor in Chief Journal of International Wildlife Law & Policy 1702 Arlington Blvd. El Cerrito, CA 94530 USA Ph: 650.281.9126 Fax: 510.779.5361 [email protected] http://www.jiwlp.com SSRN site: http://ssrn.com/author=240348 Skype ID: Wil.Burns -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
