PNNL houses a number of key science research facilities that may be used by the various projects within this Initiative. Some brief information on these facilities is provided below.

Atmospheric Measurements Laboratory
An early project of the Aerosol Climate Initiative was the development of the continuous-flow chamber capability at PNNL in the Atmospheric Measurements Laboratory. This new capability is now being used to conduct laboratory-based research targeted at reducing the uncertainty associated with representing the SOA formation and processing in models.

Environmental Molecular Sciences Laboratory
The Environmental Molecular Sciences Laboratory (EMSL) is a U.S. Department of Energy national scientific user facility located at Pacific Northwest National Laboratory. It provides integrated experimental and computational resources for discovery and technological innovation in the environmental molecular sciences to support the needs of DOE and the nation.

Gulfstream-1 Aircraft
The G-1 is a large twin turboprop capable of measurements to altitudes approaching 30,000 feet over ranges of 1500 nautical miles, and can be operated at speeds that enable both relatively slow sampling and rapid deployment to field sites throughout the world. The aircraft is configured to accommodate a variety of external probes for aerosol, radiation, and turbulence measurements and internal sampling systems for a wide range of measurements. Based out of Pasco, Washington, the G-1 is operated by PNNL for the U.S. Department of Energy to serve atmospheric scientists at DOE and other federal, state, and industrial laboratories in carrying out airborne research related to understanding atmospheric processes as they relate to the DOE's environmental missions and the global environment.
