2003 ARM Science Team Meeting

March 31 - April 4   |  Broomfield, Colorado  |  Omni Interlocken Resort

Nestled against the backdrop of the Rocky Mountains, the Omni Interlocken Resort in Broomfield, Colorado served as the site for the 2003 Science Team Meeting.

Meeting Highlights

The Thirteenth Annual ARM Science Team Meeting was held at the Omni Interlocken Resort in Broomfield, Colorado. A near-record attendance of more than 270 scientists and researchers, including 54 international scientists representing 20 foreign countries, participated in a series of plenary and poster sessions, and working group meetings.

During the opening plenary session, DOE's Office of Biological Environmental Research's Wanda Ferrell, ARM Science Director, thanked the scientists for their expertise and ingenuity, which contributed in fiscal year 2002 to improvements to climate model parameterizations as well as to site data systems, and which resulted in 158 publications in the fiscal year that featured ARM research. Tom Ackerman delivered a "State of ARM" presentation, which included a preview of a new ARM Science Plan to advance the scientific agenda of ARM for the ensuing 5 years.
