[Grad-postdoc-assn] ASP seminar this Wednesday

[Daniel Kirshbaum]

Like its forerunners, this last ASP of the year seminar is a must see.  
If the subject matter itself doesn't draw you in, please take into 
consideration that coffee, tea, and countless other goodies will be 
there for your consumption.

Title: The role of organic aerosols in cloud formation

Abstract: It is now well-established that organic compounds are 
significant, and sometimes dominant, components of tropospheric 
aerosols. Their interactions with water are important in estimating 
their effects on visibility, climate and cloud formation. In general, 
organic aerosol constituents appear to be less hygroscopic than ionic 
species, but their phase behavior is not well understood. This talk will 
review recent measurements of the hygroscopic behavior of atmospheric 
and model organic aerosols, including species with limited solubility 
and polymeric materials. Finally, methods for estimating organic aerosol 
cloud-nucleating ability in the absence of detailed compositional 
information are presented and evaluated.
