There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Timothy Raymond of Bucknell presents Aerosol-Water Interactions in the Atmosphere: From the Nanoscale to the Global Scale as part of the 2006 ChBE Fall Seminar Series
Refreshments will be served from 3:30-4:00PM
The seminar will be held 4:00-5:00PM
Abstract
Aerosol particles are ubiquitous throughout the atmosphere and have far-reaching influences on the global radiation budget, climate, visibility, and human health. These particles range in size from molecular clusters of freshly nucleated material up to visible dust particles larger than 1 mm in diameter. They may be simple particles of NaCl or composed of hundreds or even thousands of organic and inorganic compounds which vary greatly based on the aerosol source and transport history. Concentrations range from as low as 50 particles per cm3 in remote arctic areas up to millions per cm3 in certain urban locations. They affect the Earth
