(2011) used long-term ground-based measurements and the short-term aircraft observations provided by ARCPAC (in the western Arctic) to conclude that Arctic aerosol pollution has both chronic and episodic components.
During several low-altitude ARCPAC flights, a positive vertical gradient in BC mass was indeed observed in the vicinity of open leads, providing evidence for dry deposition of BC from low-altitude, well-aged air masses in the Arctic (Spackman et al.
(2011) calculated the radiative forcing from measurements made during ARCPAC in the springtime Alaskan Arctic.
During spring 2008, ARCPAC sampled enhanced concentrations of CO and PAN in aged Siberian fire plumes (Fig.
The ARCTAS and ARCPAC campaigns were the first airborne missions to use chemical ionization mass spectrometry (CIMS) to speciate inorganic bromine (Neuman et al.
The ARCPAC project was supported by NOAA Climate Change and Air Quality Programs.
