2008 ARM Science Team Meeting

March 10 – 14 | Norfolk, Virginia | Sheraton Norfolk Waterside Hotel

Meeting Highlights

Sheraton Hotel - Norfolk, VA

The eighteenth Atmospheric Radiation Measurement (ARM) Program Science Team Meeting was held March 10-14, 2008, at the Sheraton Norfolk Waterside Hotel in Norfolk, Virginia. This meeting brought together ARM science researchers, ARM Climate Research Facility infrastructure members, and selected leading scientists to review progress and plan future directions for ARM research.

Held annually since 1990, the ARM Science Team Meeting officially began on Tuesday with a plenary session, followed by a full schedule through Thursday of formal presentations by invited speakers and breakout sessions. Working group meetings and special focus meetings were held on Monday and Friday, including the ARM Chief Scientist’s Orientation for New and Current Principal Investigators. Poster session receptions were held on Tuesday and Wednesday evenings to review and discuss results emerging from cloud and radiation measurement and modeling research.
