ARCTAS<br />
<strong>Science</strong> Focus: Atmospheric Composition<br />
Sponsor: J. Crawford & H. Maring, <strong>NASA</strong> HQ<br />
Location: Alaska, Canada, Greenland<br />
The Arctic Research of the<br />
Composition of the Troposphere<br />
from Aircraft and Satellites<br />
(ARCTAS) field campaign<br />
represented <strong>NASA</strong>’s largest<br />
commitment to atmospheric research in<br />
support of the International Polar Year<br />
(IPY). Sponsored by <strong>NASA</strong>’s Tropospheric<br />
Chemistry and Radiation <strong>Science</strong> programs,<br />
ARCTAS consisted of major field campaigns<br />
in the spring and summer of <strong>2008</strong>, involving<br />
the deployment of three <strong>NASA</strong> research<br />
aircraft to the Arctic to characterize<br />
atmospheric change in this climate-sensitive<br />
region. The <strong>NASA</strong> effort contributed to a<br />
larger interagency and international effort<br />
identified as POLARCAT (Polar Study<br />
using Aircraft, Remote Sensing, Surface<br />
Measurements and Models, of Climate,<br />
Chemistry, Aerosols, and Transport).<br />
ARCTAS science objectives addressed four<br />
major themes:<br />
1. Long-range transport of pollution to the<br />
Arctic including arctic haze, tropospheric<br />
ozone, and persistent pollutants, such as<br />
mercury.<br />
