The 4th GEOS-Chem Scientific and Users' Meeting was held from April 7–10, 2009 at Harvard University. It brought together over 160 scientists from more than 50 institutions and 15 countries.

We would like to thank NASA/ACMAP, EPRI, NSF-ATM for financial support; Harvard School of Engineering & Applied Science for facilities; Brenda Mathieu and the Jacob graduate students for logistics.
