AMS Users MeetingProvides Forum to

• Get to know each other• Learn from each other’s experiences• Pool resources as a community• Provide feedback to Aerodyne for continued development• Divide outstanding problems among users to be solved quickly• Avoid repeating work that others have already accomplished• Putting our results together into the bigger scientific picture

Bottom-line: by pooling resources the AMS Users Group has successfully expanded and rapidly become an important and influential force within the aerosol community!!

There are a total of 33 presentations (12 talks and 21 posters) at AAAR using AMS data (not including late-breaking posters). These represent 5.7% of the 577 presentations at AAAR 2004.

Objectives of Meeting• Improve our data analysis procedures and

understanding– Saturday’s focus– Doug’s Tutorial

• Complete our understanding of the quantification issues of the AMS

– Saturday’s focus, with presentations from many groups dealing with different aspects of AMS quantification and calibration

• Provide updates on AMS hardware and acquisition and analysis software

– Sunday’s focus– John Jayne, Manjula Canagaratna, James Allan

• Expand the applications of AMS technology to address new scientific and technical questions and issues.

– Monday’s focus
