Short summary
Arctic atmospheric particles have important climate impacts via cloud formation and precipitation, particularly in the wintertime. We show that sulfate, formed during atmospheric transport, is within individual sea spray particles and organic particles measured in the Alaskan Arctic. Greater contributions of combustion emissions were observed when the wind direction came from the Prudhoe Bay oil fields, showing its regional influence.
