NOAA-ARCPAC
A Project of NOAA’s Climate Forcing and Air Quality Programs for the International Polar Year 2008
ARCPAC was established as an airborne field experiment in Alaska to address the four major areas of non-greenhouse-gas atmospheric climate processes in the Arctic. A NOAA WP-3D aircraft was used for the experiment, and was based at Fairbanks, Alaska.

Seeking to answer:
What are human-caused processes (other than long-lived GHG-induced climate change) that may increase Arctic warming and/or sea ice melt?
By examing:
- Lower tropospheric warming due to absorption of solar radiation by soot particles
- Decrease in snow albedo by deposited soot
- Increase in IR emissivity of clouds by aerosol indirect effect
- Tropospheric O3 forcing (local IR and global)
Where: Fairbanks, Alaska
When: late March - April 2008
How: The focus of the NOAA airborne measurement component of this project will be the NOAA WP-3D platform.
Who: Investigators in this project include researchers from several universities, industries, and governmental agencies. Participating institutions include ETH Zurich and Georgia Tech.
