Airborne measurements made in the vicinity of Barrow, Alaska during early spring have revealed relatively large concentrations of giant (>2 &mgr;m diameter) particles in the air. Their concentration varied approximately with the inverse cube of the particle diameter. These particles were not well correlated with the layers of visible haze observed. They appeared to be approximately uniformly distributed from altitudes of 0.3 to 5 km regardless of the presence of absence of arctic haze.
